Removed from service several years ago. Replaced all electrolytic capacitors. View last images showing before and after. First time turning on was with variac control. Ran for 1/2 hour and noticed one top mounted capacitor failing so replaced all. The chassis mount caps were left for aesthetics, but are disconnected. The failed cap has been repaired enough to show as original. Tubes have been checked on a Hickok TV-7 tester and values marked on them.
I’m letting go of a few things from from my collection, including this Audiotronics model 300 vintage tube amplifier amp project. Will make a killer guitar amp. If you like the Filmosound stuff, and single-ended amps, this one is great, rare and has a cool look with that front panel, just tweak the circuit and add your preferred controls. Has nice Triad power transformer, good sized output transformer, 6×4 rectifier, 6bq5 (el84) power tube, and a 6av6 preamp tube. Looks to be in stock form. Not currently in a working state.
THIS COMES AS PICTURED. I WOULD GUESS IT NEEDS THE WAX AND PAPER CAPS REPLACED AT LEAST JUST TO BE SAFE. IT WILL COME WITH ALL THE TUBES SHOWN. ALL OTHERS TO USE EIS.
The Stromberg Carlson AU-58 – a great sounding head for guitar. Original Stromberg Carlson Tube Set. The AC main cable has been replaced.. Sounds really good onb Harp or Guitar. Original Stromberg Carlson tubes. Condition is OK and to be expected for its age. There’s a serial number etched on the top of it, which seems to be common for these. Sounds great connected to a couple of 12 inch speakers and my Strat. Let me know if you have any questions. Made in the United States.

Vintage mid-1950s Heath Company hand-built Heathkit W3M “Williamson Type” mono tube amplifier and companion Heathkit WA-1 Power Supply in good working condition (see video). Appears to all original and unmolested. No hum and very good cosmetic condition for its age. Amazing that these were engineered so well that its working great after 70 years. All vintage tubes made in USA. Acrosound TO-300 “ultra-linear” output transformer. Being so old, it should be checked out by a qualified tech to replace any out of spec or obsolete components. The only issue I noticed was the multi-pin connected cable needs to be manipulated to find a sweet spot to make a connection, so there must a loose or frayed wire in cable end. Nice mono amp for your vinyl audio system or part of a tube stereo set-up. Heathkit W-3M Tube Amplifier & WA-1 Power Supply – YouTube. These are automatically added to the final invoice and I’m not able to delete or adjust them.
Up for sale, a 1954 Gibson GA-20 in excellent condition and in perfect working order. Featuring original two-tone cosmetics, a Jensen P12R speaker, and a professionally serviced circuit, this GA-20 is the perfect mid-size combo from the golden age of tube amplification. In many ways analogous to Fender’s narrow panel tweed amps of the same era, the GA-20 features a four input design with a 6V6 power tube pair, 5Y3GT rectifier, and dual triode (12AX7, etc) tubes in the preamp. Offering distinctly different voicings between the single Microphone input and the three Instrument inputs, the GA-20 is at its most aggressive via the Mic channel. While this input does offer a modicum of clean headroom, it quickly overdrives with a sizzling, chewy sound that’s extremely smooth. The Tone control has an absolutely massive sweep, actually adding a bit more gain when turned up. Maxing out both Volume and Tone knobs yields a ripping, cutting sound that interacts equally well with single coils and humbuckers. The Instrument inputs have more range in the clean signal, with a full-bodied and sweet sound that works well with a host of effects pedals. Turning down the Tone knob on this channel and pushing the Volume can achieve a very nice bark and a spitty quality almost akin to certain fuzz boxes, depending on the guitar being used, and once again diming everything out delivers plenty of richness and roar. The point-to-point circuit has been professionally serviced and thoroughly recapped with premium tubular signal caps in the preamp and F&T power supply caps. The output transformer has been replaced with a vintage-accurate Mercury Magnetics ToneClone GA20-O, mounted to the speaker frame, while the original power transformer is intact, mounted to the back of the chassis. The speaker is the original Jensen P12R alnico magnet driver which has a dark blue/green frame. The speaker has been recently professionally reconed, and the date code on the edge of the frame is from the 9th week of’54. The original two-tone covering exhibits limited wear (particularly when considering the fragility of this material compared to a conventional tolex or tweed), primarily concentrated around the edges, and half of the gold Gibson badge is still intact on the amp’s face. The graphics on the brown faceplate are clean, the brown chickenhead knobs are present, and the leather handle has been replaced.
One side was professionally restored recently due to not correctly outputing audio. I’m located in Staten Island, New York. Built by Robert Judge from Judge Amps in Somerville MA, wonderful sounding, built from scratch. Each block is very heavy, especially for how small they are: about 34 pounds each. THEY ARE ONE OF A KIND, BEING RARE IS AN UNDERSTATEMENT. You’ll be the only one around with a pair of these, in the world, these do not exist anywhere, so, if your an audiophile tube person, or just a HI-END tube person then these are definitely for you.
Vintage The Fisher 500C FM Tube Stereo Receiver Amplifier (Most Original Tubes). Pre owned in working condition. I assume from the age, a cleaning and deoxit could be usefull. This has many original tubes The Fisher Germany. Missing gold round knob end plate on speaker selector knob. When testing the balance knob when turned all the way to the right does not direct audio just to right speaker. Left is fine, and when balance is centered, both speakers play correctly. I assume the potentiometer knob needs deoxIT due to age and oxidation. Please see video and photos, if you have any other questions, I will try my best to answer. See pics above.
Everything appears to be there to make a self contained guitar amp, or head. Uses a 6×5 rectifier, 6v6 power tubes, and 6sn7 with dual 6sc7 preamp tubes – tubes are all vintage.
