Slowly powered up with variac...WORKS! Eighty-year-old caps, and no problem!
Added 3-conductor power cord, and had to jump out the Volume pot because it's frozen (no loss, because amp is not very loud).
Tubes are 6N7, 6C5, 6V6, 5Y3.

Very cool! They don't make them like they used to, eh?
Re: 1940s Oahu amp
Amazing! Is that one of yours now or is it just passing through?
Re: 1940s Oahu amp
Cool. Liking that pre-Rola Rola field-coil.

Nice! A blast from the Hawaiian guitar past! Deoxit applied to the bushing and some gentle persuasion might free the volume pot. Working, but I'd bet replacing the electrolytics would really wake it up.

That's a bummer. I've serviced a couple of original EH150s. Very cool amps as well. I dig the cabinet design of that Oahu though.
