Old Kay amp needs attention
This is a very old guitar amp probably from the late 1940's. I believe it is single ended in that it has an 80 rectifier tube, a 6C5, a 6N7 and a 6L6. The socket for the 6L6 says 6N6. The amp works but I can see on my variac amp meter the current draw goes down instead of up when I strum the guitar. This seems odd to me as all other amps I've tested this way increase the current draw. It also seems to have a large current draw at idle, (no input signal) at .9 amps. The amp has had some work done, perhaps a lot as much of the circuit has been rewired and new capacitors. What if anything is out of the norm here? In other words shouldn't the amp meter rise with a strong input signal? If so what might be the reason it's decreasing?
Is this a good question?
