Genuine Fender Output Transformers


p12

1. Champ, Vibro Champ, Bronco and other small single-ended amps using one 6V6GT, 6BQ5, 6AQ5 and other tubes. Actually, this one KICKS ASS with a single 6L6GC, 5881 etc. too. Rated at 10 watts, wound optimally for a single 8 ohm speaker but works fine into anything between 3-16 ohms. These NEW genuine Fender transformers fit the original mounting centers (2.375") in most old Champs but they're taller (approx. 2.25" tall) than the originals. They feature the same 'open frame' construction found on '50s-'60s models; check out that funky cardboard and waxed paper bobbin! Try this iron in your old Champ or other small single ended guitar amp; you may notice better bass and a cleaner, louder more full bodied sound. These also work well in '50s tweed Princetons or in custom/experimental designs using a single 6V6GT; SEE THE "HOW TO..." PROJECT ON THIS SITE. GENUINE FENDER. SALE! EACH $40.


p13

2. Princeton, Princeton Reverb and any other small amp using a pair of 6V6GT, EL84, 6AQ5 or similar tubes in push-pull. Rated at 12-17 watts into an 8 ohm load (optimally...) but these will work into anything from 4 to 16 ohms; try it yourself. Fine for restoring older brown and 'blackface' Princeton, Princeton Reverb and Super Champ; this transformer fits these vintage amps exactly. Also good for fixin' Supro, Silvertone and other nice small amps in this power range. Primary has three wires with standard color code; blue and brown plate leads with a red center tap. Single 8 ohm secondary has standardly coded black and green wires. Upright mounting type with 'clam shell' bell ends. Measures approx. 2,25"X2"X1.875" tall.

Steve's Mailbag: Is The Fender Deluxe Reverb Output Transformer Great Or What?

"Hi. I bought a Deluxe Reverb output transformer from you the other day and wanted to let you know that I successfully used it as a replacement in a Marshall DSL201 amp (2XEL84). It makes a great replacement, primary impedance is perfect, primary ohms perfect (didn't even require changing the bias), sounds better than stock, should be a lot more reliable since it's at least 50% heavier/larger, scoped it and verified it's generating the full 20 watt output as before. It cleanly fit the chassis by drilling 2 screw holes. The only caveat is that it's 8 ohm output instead of 16 (a good thing to me...). Just wanted to pass on the info so you can offer your customers an upgrade to the stock Marshall xfmr which is guaranteed to toast when you play it hard. I had no idea that 6V6 and EL84 were electrically so similar until this exercise. Regards Mike S. BTW-The E.I. EL84s are holding up well in the DSL201 even though played really hard (hard enough to toast the xfmr) and they sound great. My frame of reference for "sounds great" is my '65 Deluxe with Mullard GZ34, RCA 6V6s, Telefunken 12AX7s, and yes the E.I's in the Marshall really do sound good even compared to the NOS'd vintage Deluxe. And since both amps have Celestion V30's it's a fair sonic comparison..."

ONE OF OUR ESTEEMED CUSTOMERS, MARK WHITNEY, WRITES: "...the Tonemaster output transformer was also used earlier in the red knob The Twin. The orange and white pair were for a low level unbalanced XLR out." Our customer ED SMITH WRITES: "Thought I would add one more point on the extra output taps. I nocited the comment from your esteemed customer stating that those taps were used for a balanced output on "The Twin". That's absolutely correct the only thing I would add is the white wire is the "in Phase" signal (pin 2 on an XLR jack) and the Orange wire is the "Out of Phase" signal (pin 3 on an XLR jack). Fender typically left pin 1 open on those. Someone might consider adding a ground lift function dependent on the application. Fender listed that connection as a +3dB level."  NICE IRON FOR BUILDING POWERFUL 6L6 AMPS WITH MULTIPLE OUTPUT IMPEDANCES? GENUINE FENDER PART #026478. SALE! $69.

F.Y.I. FENDER TRANSFORMER CROSS REFERENCE LIST:
Transformer Info,Duuuuuuuuuude

Steve's Mailbag...A Transformer Question.
Q. "I would like to make better selections on the output transformer that I use for my guitar amp projects. I have been building, studying and working on amps for just over two years. As I have learned more, I have also had more questions and the one at the top of my list now is. If I have an amp running in push-pull how do I determine the primary impedance, of lets say two 6L6s (I have an RCA tube receiving manual)? If you have a quick answer let me know or if you could tell me where to find the info, I don't mind looking for myself. I also understand that the selection of the output transformer is subjective and what sounds good to one may not sound good to another and the construction also affects tone. I would just like to take some of the mystery out of selecting output transformers for the amps I build. Thanks for your help and all the free info on your web site, its great. I also buy a lot of transformers from you."
A. There's quite a bit of print material on choosing/selecting primary impedances for tube circuits. SAMS Photofacts for vintage tube audio components by Scott, Fisher, Bell, Eico etc. give some very valuable hints for choosing output transformers. SAMS can often be had for little or no money if you find a TV repair shop that wants to get rid of 'em. This takes some leg work but at one time I'd located so many Photofacts that I started giving them away to friends. Old transformer catalogs by Triad, Hammond, Thordarson, Merit, ADC, Dynaco, Acrosound and others often include good hi-fi circuit schematics using their iron and they usually also show suggested primary impedances for various groups of tubes. You should also buy every old issue of Radio And TV News you can find, since these, another electrogeek mags from the late '40s-early '60s show tons of tube amp projects, often more than one per issue. Buy back issues of MJ from Japan. These cost me an arm and a leg (over TWO HUNDRED BUCKS PER YEAR...) but it was worth every penny. MJ has tons of cool tube hi-fi projects, usually showing several different operating points for their circuits with suggestions for matching primary impedances. Even if you can't read Japanese, you can still figure out the important stuff. Old electronics catalogs will often list audio output transformers of various kinds, so you should also be on the lookout for those. If you've still got some bucks to spend, consider picking up copies of the RADIOTRON DESIGNER'S HANDBOOK 4TH EDITION and AUDIO CYCLOPEDIA from the late '50s-early '60s. Another fairly expensive but essential book would be the Rider PA Manual; this one is rare but you may find a copy to check out in your local university Engineering library? Reprints of audio amplifier circuit books by M.O. Valve, Mullard and Philips are some of my favorites, since these favor the EL34, KT88, EL84 and other fine sounding European tubes; all of these will show the required primary impedance for their projects. There are also some web sites by various transformer manufacturers giving some primary impedance information; just search for AUDIO TRANSFORMERS and you'll have some more stuff to look at. There really is no mystery to selecting output transformers but choosing the one that pleases YOU is going to be fairly subjective and involve lots of experimentation and A-B testing. Best of luck tryin' 'em out. By the way, the 'textbook' primary impedance value for a push-pull pair of Class AB 6L6GCs is around 6.6K. The most popular primary impedance for a pair of EL34s is around 4K. Amps using a push-pull pair of EL84s or 6V6s usually use an output transformer of around 8K.
