Hi All,
This is my first post here, so be gentle
It's been a while since I've done any electronic restorations. A friend of mine picked up a 41-290, and I offered to help with the electronics. I've re-capped it, and replaced all of the rubber wire in it, including the wiring to the loudspeaker/field coil (which was frayed and shorting where it goes through the chassis). I currently have audio going all the way to the input of both 41 tubes, but nothing coming out of either.
I am not sure where to look. The schematics I have at my disposal are incomplete at best. If anyone has any ideas where to look next, they'd be greatly appreciated! Also, does anyone know what the voltages at the 41's are supposed to be?
