Ok, I finally got around to checking the voltages on the 41's. The grid voltage (pin 3) is 175v on both tubes. Plate voltage is not there. (-1 or 2 v). I know there's audio at the input to the tubes, confirmed with a test speaker. What should the voltage there be? I did replace the crumbly speaker wires, and I'm beginning to wonder if I got something backwards... Thanks in advance for any help!!!
