Dumont mono tube amp

Vintage Asylum

Classic gear from yesteryear; vintage audio standing the test of time.

Since I'm a professional tube amp tech, people occasionally give me things they'd otherwise throw out. This mono amp apparently came from a 1957 Dumont phonograph console. Transformers have a 352 Essex EIA code. Based on the tube number sheet, which was saved, it seems to have had a remote control module that contained a single 6AV6 as a phono preamp stage and that plugged into the empty socket on the amp.

It's an extremely simple amp with 2 x 5Y3, a 12AX7 paraphase inverter, and 4 x 6V6 cathode biased in parallel push-pull. I found one other photo online of what seems to be the same amp, but that's about it. I thought the iron looked like it might be good...
