Request: Help with amp ID

It's my first time so be gentle :jam: I came across this amp and would appreciate any thoughts on a year/ID. The tubes are a 35W/4
half wave vacuum rec and 2 12AV6 that look to be original NEC manufacture.

The closest I've been able to find is a similar one sold on Ebay in which the seller suggests Teisco, but I'm not so sure.

I'd say based on the tolex, the knobs, the name and the general funkyness that it's the same amp as on eBay, and it does look very Japanese....

how does it sound? :mrgreen:

I haven't been able to fire it up, I'm waiting on a 50c5 delivery. Part of me wonders who in their right mind designed a guitar amp as the old widowmaker radio setup? This could easily turn the instrument cable into a death wand? I'm debating whether or not to just order all new caps as well.

Is it possible that this would be a Teisco A-3L based on the schematic pre 1955? I think the case for brand of Teisco is because of the way DeVille is written looks like the way they write Melody. Also the Audition has a similar body type but the electronics are heavily upgraded.

Il look a japanese made amp sell around $49.9r in the end of '60

With 35W5 +50C5 + 2 X 12Av6 = 110 volts serie heater.

This amp may not have a power transformer . Very dangerous to play with. You need to mod with a isolation transformer.
Use on well isolated floor with good shoes and don't touch to any steel.

I was able to get it running, some of the output caps are bad, no surprise. I think that's why the control panel has a dent, and a missing tone knob but it'll be an easy fix. I did undergrad in EE/CE. This thing is very dangerous. I think the real danger without mod, would come from touching anything else properly grounded to an outlet making your body part of the circuit. https://youtu.be/9oxvE7KeevQ
