Up for sale here is this gorgeous vintage power supply. It looks like it could power a tube amplifier, but otherwise you could part it out and use the parts in a tube amplifier. This has an extremely nice homemade wood case, as well as the following parts. Simpson DC Volts Meter (0-500). Weston Model 506 DC Milliamperes Meter (0-300, made for US Signal Corps). 3 Toggle switches (1 front, 2 rear). 6 vintage heavy-duty binding posts (3 black, 3 red). Rear AC jack (no cord, sorry). Huge Sprague Atom capacitor. Thordarson Choke (I think it’s marked C330). UTC H-83 power transformer (looks incredible, rated at 115VAC primary, 6.3V 5A secondary, 5V 2A secondary, and either 670v 130mA or 600v 140ma secondary). A few misc resistors and other parts. Hand-drawn schematic on inside. This is an incredible piece of gear, and I really don’t want to part it out, so I thought I’d put it up as a whole before I cut it up. This is untested and I would probably replace the caps or at least bring them up on a Variac for safety. I will guarantee the power transformer to be good. Please see my pictures for details. If you have any questions, please ask. I have more transformers and other vintage electronics listed–feel free to take a look!

Vintage Tube Amplifier PA Army Navy Surplus Power Supply 1940s RCA SCOTT 6l6

Vintage Tube Amplifier PA Army Navy Surplus Power Supply 1940s. For sale untested but looks to be complete. Ive done some research and based on the type of knobs and look I believe this may have been manufactured by Scott or RCA possibly in the 1940s. I didn’t plug in and test and Ill leave it to someone who is more experienced with tube amps. Ive collected many vintage stereo receivers over the years and thats my forte so i will have to let this item go to someone interested in powering this beast up. Super cool but its pretty large and heavy for me to store. The power supply half weighs in at 74 lbs. The control half weighs in at 61 lbs. Grand Total Weight of 135 lbs. Please take in to consideration the weight of packaging materials. Each of the two halves have a dimension of 16″ x 21″ x 12 inches. The case is made of heavy gauge aluminum and it is still sturdy and not rickety. The meter says “Hoffman Radio Corp”. All tubes are made in the USA by RCA, Sylvania, Gm Delco, and CBS.
