The Saga Continues

Continuing the saga of how a WWII Navy fighter pilot-turned-entrepreneur to design and build his own brand of electric guitars in the 1960s. Guitar player and author of the book series Guitar Stories, Michael Wright tells the unique story of Patrick Murphy and Murph Guitars. The story is told here by Michael Wright in Vintage Guitar Magazine.


Silvertone 1428 (Sears 60BXL) Solid-State Bass Amp

60-Watts of Transistor Power! (meh)

The Sears 60BXL (labeled as Silvertone model 1428) was a electric bass amp similar in design and appearance to guitar and bass amps built by Danelectro in the late 1960’s. It appeared in the Sears Catalog from 1971 through 1973. According to the catalog, the 60BXL was a two transistor-powered 60-watt (marketing hype) bass amp with a 15-inch speaker. It seems that very few of these amps were sold, maybe because the more powerful 200BXL met the needs of electric bass players.

Not much is known about these amps; they are rarely seen in the wild. Here is an image from the 1971 Sears Catalog.

Silvertone 1437 Shark Fin Electric Guitar

Gallery Silvertone 1437

Also known as the Teisco ET-460 or K4L “sharkfin” guitar.

Check out the photos of this super cool, vintage 1969, made in Japan, Sears Silvertone 1437. The 1437, more commonly known as the “Sharkfin Guitar,” has a mean-looking hand-carved body, four (4!) pickups, and a machine-striped solid aluminum pick guard. Sold in the U.S. by Sears & Roebuck in the late 1960s and early 70s as Silvertone model number 1437, it’s known in Japan and other markets as the Teisco ET-460 or Teisco 4KL. Could have been sold elsewhere under other names as well?

Made in the now-defunct Teisco factory of Japan.

This particular guitar was recently purchased from eBay seller mwbutler. The excellent photos below are by mwbutler.

Silvertone 1422 (Sears 40XL)

Silvertone 1422


Update: Just added some new shots of the chassis, tubes, board, Orange Drop caps, Fisher speaker, etc.

The Original 40XL

This page is dedicated to photos of our ’69 Silvertone 1422, also known as the Sears 40XL. We recently acquired this amp and found it to be one of  the nicest 40XL’s we’ve seen in many a year. This Made-in-USA amp is totally original, right down to it’s late 60’s dark olive vinyl, green sparkle grille cloth, and a 12-inch Alnico magnet made by Fisher. The only cosmetic damage we could find is a bump (dimple) on the cabinet edge, right side of the control panel, and a chip off one control knob.

The 1422, or 40XL, was marketed by Sears as a 40-watt, 12-inch, combo tube amp for guitar. It features two separate input channels, and built-in reverb and tremolo. The reverb and trem are controlled by a dedicated foot switch. Sears advertised these as 40-watt combo amps. But in reality, the two 7189 power tubes put out around 20-watts or less. In fact, the features and chassis layout suggest that it could be an American copy of a the mid-60’s Marshall Model 1974, which was an 18-watt combo using two 6BQ5’s (EL84’s).

Summer of ’69

This amp was built, sold, and first played in the Summer of ’69. The code on the CTS potentiometers read “137-6919.” Decoded, that means “137” = Mfr’d. by CTS; “69” = Year Mfr’d. (1969). “19” = Week Mfr’d. (2nd Week of May).

How Does It Sound?

Well, it’s a loud 18 to 22 watts, that’s for sure. HUGE in the mid range, solid in the bass range, but not too sparkly or chimey at the high end. Poor speaker sounds like it’s wearing a heavy wool sweater. And there is a noticeable 60-Hz hum. But we will dig into it and find out what’s wrong.

Major improvements! We took the chassis out of the cabinet, cleaned and tightened all the loose connections, and relocated one unshielded cable sitting too close to the transformer (will completely remove that later). Now, the amp is almost silent when idling, the 60-Hz hum is completely gone, and frequency response at the high and low ends have improved!

These photos are little rough, and I hope to upload some better ones in the near future.

I have a 1422 from late 60’s early 70’s? It too is in very nice condition. All original tubes, but missing a knob. The volume on channel one is quite low but channel two roars. True, it does sound like its wearing a heavy wool sweater! I was wondering if I could change out tubes for a better high gain sound? Shoot me an email and I’ll send some pics, and any advice would be much appreciated!!


alex September 23, 2013 at 8:32 pm

Hi Ed,
Would love to see photos of your amp. This one has a lot of gain already. Not certain which tubes to try for even higher gain. I think the speaker might be the weakest part. Planning to try some different speakers to hear what happens…?


mike March 31, 2014 at 12:02 pm

I just picked up a solid state 40XL at the goodwill for $9. Sounds great with mu delta king semi-solid body and they look great together.

A bit of wear, but love the tremolo feature I also played a round with it and found with the 2 chanenels that I could actually use it as an amp and mini PA if I balance things right in a pinch. The tremolo works on your voice too, kind of like a 70’s ( I think that’s how old it is without the tubes) W.i.l.l.i.a.m effect.

Any chance of finding a manual on this baby on line anywhere? Is it repairable if it craps out, being it’s so old??? Any review info or thoughts would be appreciated.

Let me know


Mikey March 14, 2015 at 11:11 am

@mike — It is most certainly fixable. I took mine into the local shop (Columbia, MO USA), and they fixed the reverb, changed the tubes, and installed a 12″ blue dog speaker that I brought in. I also had a proper 3 prong cord installed. The amp is now my mainstay, I use it always!


alex March 15, 2015 at 9:55 am

Excellent! Thanks, ~alex.

Tim September 27, 2013 at 6:41 pm

Hi Alex,

I just got one of these and was wondering if you have a schematic. Mine is not in the great condition of yours, but seems to work fine. No pedal though. Please post your findings about the different speakers you try!



alex September 29, 2013 at 10:09 pm

Hi Tim. No schematic yet. Hopefully I can make one (with some help!).

I’m pretty sure that the original speaker can’t handle the power of this amp. I disconnected the original and patched this amp into another cab that I have. That made a big difference! I’m planning on ordering a G12-H-30 (Greenback) from Ted Weber.


Tim September 30, 2013 at 7:32 am

Thanks Alex! I took the head apart this weekend and just wanted to let you know that there is an 8 ohm speaker tap on the board. It has a red wire going to it and it’s right next to the 4 ohm, where the speaker is connected. Also, I tried jumping the channels, and with both channels turned up there seemed to be more presence and touch sensitivity, seems like the clouds lifted some. I’m also going to try a Celestion, I have an old G12H25, but it’s 15 ohms. I’m going to try it on the 8 ohm tap and keep my fingers crossed!


alex October 1, 2013 at 10:14 pm

Thanks, Tim. Good call! I did not notice the separate 4 and 8 ohm taps. I also tried jumping the two channels and noticed a slight improvement.


Tim October 2, 2013 at 7:03 pm

I wasn’t able to use my old speaker, but I did put in a g12h30 anniversary and it was more clear and gave it more Marshall growl. My try a Jensen next.


john November 18, 2013 at 11:02 am

Has anyone discovered a schematic for the 1422 ? I have one and am trying to figure out if it’s 4 or 8 ohms ? I have a 4 ohm Fender speaker I would like to put in it.


alex November 18, 2013 at 9:33 pm

I’m *pretty sure* the the original wiring is for a 4 ohm speaker. But please see Tim’s comment above about both 4 ohm and 8 ohm taps from the output transformer. It’s nice to have options :-)


john January 20, 2014 at 10:00 am

Still searching for a scematic for the 1422. Having distortion problems in the tremelo circuit. My tech guy can’t find one either. The tremelo does not seem to kick in unless the Strength knob is at 12 noon or higher. When the speed knob is turned past noon, ugly distortion is present. Any ideas ?


alex January 20, 2014 at 9:41 pm

Sorry, John. Haven’t been able to track one a schematic for the tube version of the 1422. I recently ordered the repair sheet and schematic from Sams Photofact, but what they sent me is for the solid-state model.

Did you try replacing the 12AX7 tube that drives the tremolo circuit? If it’s not the tube, then the problem might be a capacitor in the circuit. I fixed the non-funtioning tremolo on my 1421 amp by replacing one of the caps. I think it was one of the caps that was soldered to either the Speed or Depth knob. Now it works great.


Jim Cord January 16, 2015 at 9:52 am

I know this is an old post, but I’m wondering if by chance if you still have it, could post the SS schematic you were sent in error?

I just (mistakenly) bought the SS version, because I was over zealous in my blind compulsive buying mode and failed to examine the photos throughly enough; had I done so, I wouldn’t have overpaid for this tube-wannabe.


alex January 16, 2015 at 7:34 pm

I will see what I can do to send that to you.



Steven March 5, 2016 at 10:00 pm

Any chance I could get the schematic for the solid state?


Steven March 5, 2016 at 10:02 pm

I’d love a schematic for the solid state if possible


john January 20, 2014 at 10:49 am

Also, would the tremelo circuit be the same in the 1421, or 1423 ?


alex January 20, 2014 at 9:45 pm

No. The circuits for the 1421 and 1423 are entirely different. The 1421 is all point-to-point hand soldered. The 1423 is solid-state; so no tubes at all. The 1422 is a hybrid because it has a printed circuit board and tubes. That makes it unique in that series.

Did your tech remove the printed circuit board and test all the caps, resistors, and solder traces?


john February 4, 2014 at 11:18 am

Yes. Looks like a cap, so I told him to replace all of them.


john February 6, 2014 at 8:55 am

Caps replaced, tremelo circuit still distorting. Any other ideas ?


Jake March 4, 2014 at 9:05 pm

Nice specimen!

I just received a 1422 off ebay today and noticed that instead of original tubes (which the seller stated they were) it has 2-EL84s replacing the 7189s and ECC 83S in place of the 12AX7s, all JJs. I read somewhere that the EL84s and the 7189s are used for different voltages in the circuit and shouldn’t even work when added. The seller is playing dumb and I can’t find out if something was modded, or everything is fine, or something seriously bad is going to happen if I don’t make sure the voltage was adjusted.

Any thoughts?


josh June 20, 2014 at 2:10 pm

I just purchased a solid state 40XL. I haven’t received it yet. Are they compatible with modern 2-button footswitches? I have a 10XL with the original tremolo footswitch but I want to control reverb too.


alex June 21, 2014 at 7:16 am

Josh, congrats on the new 40XL! The 40XL uses a two-button switch to control reverb and tremolo, and has a single 1/4-inch two-conductor plug. Like a 1/4″ stereo headphone plug. See it here: http://www.tonegems.com/silvertone-1422-footswitch/



alex June 21, 2014 at 7:43 am

You can purchase a similar foot switch online or in music stores for around $50. Or you could buy the parts and build one for about $20.



Fran December 6, 2014 at 8:16 pm


I just rebuilt a Sears Silvertone XL40… cabinet mostly and professionally done on a CNC. Will post pictures. I, too, am getting a screeching trem and the reverb is’t working, although the verb does boing when moved… so some further scrutiny is necessary. The finish of the cabinet is wood, stained and toned. I made it a little larger than the original and also plan to make another the same size as the orignal with tolex covering. I also remade the control panel graphics. Looks real nice and a lot of tube power. Just have to get the trem and reverb right. I recall, trem and verb were working before I tok it apart. All for now.


alex December 7, 2014 at 7:44 am

That’s great! Please keep us posted. Send some photos of your project; we’d love to see how the cabinet turns out.



Fran December 12, 2014 at 6:20 pm

Cabinet is almost done… working out some bugs in the circuitry… probably needs newer tubes… all else seems to be clean and intact. Assemling this weekend and then will take pictures. Note that I enlarged the cabinet some; however, I have recently redigitized it to spec. I will make a second cabinet with a tolex wrap and make the electronics (or head) a separate entity. Thanks.


Fran December 24, 2014 at 10:37 am

Emails with pictures sent to your addy and a question. Let me know if you received them, Alex. Have a very Merry Christmas. BTW, I was with the owner of the Danolectric tradename last evening. What a great fella!


alex December 27, 2014 at 12:53 pm

Happy New Year! I did not receive your photos :-( Please try again.



Fran December 27, 2014 at 1:12 pm

Note, photos coming from another addy and just sent 4:06 EST 12/27/14. Also, could you elborate on the wire near the transformer that was causing the 60 cycle hum and all you did to resolve that. I, too, have the hum. I do not plan to make my unit 3 wire because I like the flexibility of reversing the plug polarity with a 2 prong…. unless I add a switch for that, or go to 3 wire and use an adapter. You ground to chassis, right? Someone told me the problem with my trem could be caps and not the tubes. Any opinion on that? Still waiting to test the tubes. I have a vintage tube tester now, but I may have to change some resistors to get it working. properly… as it’s been sitting for a good many years.


Fran December 31, 2014 at 4:59 am

I have decided to take inventory on the PCB components and, also, draw up a new PCB and etch a new one for the beast I’m working on. When I’m further along, I will post or link the data and PCB drawing. For now, there are two blue-ish colored capacitors and on the south end appears to be some sort of (tan) washer that I thought might be the cap bleeding. There are no pictures above of the component side, but if anyone knows anything about these two caps, let me know if what I am seeing is a bad cap (I have not tested it). Alex, I sent you pictures of the solder and component sides. Caps I am referring to are labeled C2 and C17 respectively. Thanks.


Jim Cord January 16, 2015 at 9:39 am

Just got a smack in the face; bought a 40xl from a charity auction, was all giddy because I (thought) got a great deal on a coll retro (I thought) tube amp.

Well, in my blinders-on compulsive buying madness, I failed to note the language on the warning lable (which was pictured in the listing) stating:
“…..does not contain any tubes or user serviceable parts…”

Yep; instead of a great deal on a great little tube amp, I overpaid for a Solid State door stop.

I guess that may be a bit harsh, as I’ve just umboxed it at work, and haven’t actually plugged in yet.
I did pop the back and examine the innards (through the nest of cobwebs) and it looks like a nice wiring job, and if nothing else, probably some good vintage parts to harvest for one of my upcoming pedal builds.

Anyone own the SS version? And if so, what are you’re thoughts on it?

I plan on giving it a good clean up, and see how it sounds.

If it’s as underwhelming as I’m pessimistically assuming, it might actually be the perfect opportunity to take the next step in my DIY education and take a shot at gutting it and building the original tube version.

Now to poke around here, and everywhere, to try finding the schematic for it.
I’m guessing it can’t be too complex; but I’ve been wrong before… recently in fact


alex January 16, 2015 at 7:42 pm

Well, the SS version is nothing like the tube version, but might have an interesting tone all it’s own. I believe it’s an early use of the printed circuit board, but with full size components (capacitors and resistors) on the board. Kind of a solid-state dinosaur.



Michael November 9, 2015 at 2:16 pm

I realize this might bit too late, but Jim… don’t trash that SS 40XL. Sure it doesn’t have the same warmth as the tube version. But with the right guitar, and couple of well chosen pedals, you can get some very pleasing tones from it.

I’m playing an Eastwood P-90 Special through my SS 40XL. And with just a touch of distortion, from my Boss DS-1, it sound pretty damn good.


alex November 9, 2015 at 10:54 pm

Thanks Michael!

Modified Silvertone Model 1421 Amp – Part One, The Tear Down

Sears 10XL Silvertone 1421 Original Speaker and Baffle

From the tail end of the vacuum tube era, a real Tone Gem in the genre of garage band tone.

Editor’s Note: This is Part One of a two part series on modifying the Silvertone 1421 guitar amp. This article is a work in progress, so please check back for additional info and updates.

The 1960’s Silvertone 1421 Combo Tube Amp (also originally sold as the Sears 10XL) is a great little vintage tube amp. It’s compact size makes it easy to carry to practice or a to small venue. It’s low 10-watt tube output (actually, closer to 5-watt) is perfect for the recording studio. It has two instrument inputs going into one channel, volume and tone controls, and a fantastic 12AX7 tube tremolo circuit, playing out to an 8-inch speaker. The sound here is definitely in the garage band category, but you can coax some great sounds out of this little guy.

The all-tube version of this amp was made from 1968 to 1972, and was later replaced with a all-transistor (solid-state) version in 1973. I picked this one up off eBay a few years ago. It’s a 1970 model and is all original, except for the brown speaker grille fabric (which is ugly!).

Below is a photo of my Silvertone 1421 after it first arrived. The vinyl covering, the controls, the faceplate were all in excellent condition for its age; no tears or scratches. The original vinyl handle was flexible and intact. The only problem this amp had was a stuck (frozen) power switch. I replaced the bad switch with a new heavy-duty toggle, and replaced the old two-prong power cord with a new grounded cord. When I powered it up for the first time it was amazingly quiet for an old tube amp.

1970 Sears 10XL Silvertone 1421

The knobs and faceplate were in great condition. The handle was still flexible and firmly secured to the cabinet. But the original toggle switch stuck (frozen).

Silvertone 1421 (Sears 10XL) Tube Amp

Vintage 1971 Silvertone 1421 (Sears 10XL) Combo Guitar Tube Amp

This great little combo tube amp was built by (who?) and sold through Sears and Roebuck in the late 1960′s and early 70′s. It was originally sold as the Silvertone Model #1421, and in later years as the SR 10XL, and lastly as the Sears 10XL. Oh, the photo of this amp looks innocent enough, but, this is one serious sounding tube screamer. And you won’t usually find them as nice as this one!

Quick Info

Summary: A 10-watt tube combo with tremolo and 8-inch speaker. Hand-wired. Lots of midrange growl that transitions into a creamy overdrive. Great for classic and indie rock, jazz, blues, country and rockabilly. Use as a practice amp or at small venues. Perfect for recording.

Pluses (+): Vintage British, Vox-like, valve sound in an affordable practice amp. Compact and lightweight.

Minuses ( – ): Cheaply constructed lightweight cabinet and thin vinyl covering. The original grille cloth was fragile, and most are completely deteriorated by now. Loud enough for a small venue (i.e. coffee shop) but not for anything larger.

Surprises: 1) The 7189 output tube! This is the higher plate voltage version of the EL84 tube made famous in British amps of the 60′s; and 2) The 8-inch Oxford Alnico speaker sounds great!

Value ($): Depends on the condition and market demand. I have seen them run from $100 to as high as $500.

Similar Amps: The original 1960′s Vox AC4 practice amp. Nothing else in the Silvertone line is similar.

The Complete Silvertone 1421 Review

(Stay tuned… this section under construction)

The 1421 Photo Gallery

This amp is in fantastic condition for it’s age. It even came with the factory original vinyl dust cover. It is all original, except that I replaced a broken power switch, and then replaced the old 2-prong power cord with a safer grounded cord. The tubes, chassis, speaker, cabinet and finish are all in perfect condition — sans for the cigarette-sized hole burned into the original grille cloth (not by me, it came that way!).

Silvertone 1445 Mosrite Surf Guitar

A Vintage 1970 Silvertone MIJ Copy of the Mosrite Guitar

Silvertone 1445 GuitarThis crazy looking solid-body electric guitar is ready to play surf, jazz, classic rock or county, and is simply a kick to play! The exquisite Silvertone 1445 (I mean, by dept. store standards of course) was hand-crafted by Teisco in Japan for Sears. The body style is an excellent Teisco version of the 1960’s Mosrite of California guitar played by rock Hall-of-Famers, The Ventures (Walk, Don’t Run and Hawaii Five-O).

Sears 1969 Catalog Page 929The Silvertone 1445 first appeared in the Sears catalog in 1968, and hung around in a few variations through the early 1970’s. It has three very loud single-coil (“Hound Dog”) pickups wired in series just like the old Danelecto models. The fast, low-profile solid Maple neck with Rosewood fingerboard sports medium to low action and is easy to play. The growling Teisco “Hound Dog” single-coils have lots of bite, and the solid poplar body has plenty of sustain. Of course, the single-coils and non-shielded wiring can be a bit noisy if you’re not careful, but easy to avoid. And I must say that the hand-painted sunburst finish over the flamed Maple; the contoured German carve body with tortoise shell pickguard; and intricate triple-layer celluloid binding makes this guitar a stunning sight to see.

The 1445 represents the pinnacle of Teisco’s contribution to the Sears Silvertone line. All high quality materials and workmanship. It has the following specifications and features:

  • Body: Morite-style, celluloid bound, fully contoured, flamed Maple over basswood with German carve; sunburst (yellow-red-mahogany) high gloss polyurethane finish; tortoise shell celluloid pickguard.
  • Neck: Bolt-on solid Maple neck with Brazilian(?) Rosewood fretboard, Pearloid block inlays and triple bound celluloid edge (w/b/w); 25½″; 22 frets with zero fret; 1-5⁄8″ at nut.
  • Pickups: Three Teisco single coil “Hound Dog” pups wired in series (loud, louder, loudest); 3 slide switches plus tone boost switch for 7 pup combinations; 3 volumes and 1 master tone control.
  • Headstock: Solid Maple; black nitro-lacquer finish; block style logo.
  • Tuners: 6 in line; sealed; made in Japan.
  • Vibrato: Teisco tremolo bar.
  • Bridge: Teisco adjustable roller bridge; chrome cover.
  • Dimensions: Length 41½″; Body 19″; Upper Bout 12½″; Lower Bout 14½″; Thickness 2″ at base of neck.

Here are some photos of the 1445 taken with the Silvertone 1421 (Sears 10XL). The 1421 is a 10-watt tube amp that was also offered by Sears around the same time. These two instruments were often bundled and sold together as a set around Christmas time (the Sears Wishbook).
