This amp looks like it has been in a time capsule. I would guess it is from the early to mid-1940s. Anybody out there have a clue? The tubes are unfamiliar and the socket pin count is squirrel-y, with extra cap connectors on some of the tubes. Each tube also has a three piece “man in the iron mask” shield that clasps around it.

The construction is so bullet-proof that it is no wonder it survived. It has a field coil speaker that predates the common use of permanent magnets. This field coil also doubles as a power supply choke. Ingenious! Beautiful simplicity, and it sounds terrific to boot. Gutsy, yet open.

Hey there, I just got one of these too, and am wondering how much work, if any, I should have done on mine. Did you ever figure this amp out? if you still have it, you can date it by the speaker codes

Thanks for your post. We worked out the issues with this amp and it sounded great! It was a repair, so we don’t have it around anymore to date it. They just don’t make them like this anymore. Well worth keeping going in our opinion.
