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.

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.
