How to troubleshoot circuit board
UEEEL0014 Isolate, test and troubleshoot low voltage ...
, (ii) with the wires short and close to the board (this is mostly important at higher ac frequencies, but excessively long wires contribute to messiness) and (iii) in a configuration closely following the circuit schematic. All this will be very helpful when you need to troubleshoot a dysfunctional circuit.

Even the printed circuit board is original. You can see on the front there are 2 RCA jacks, a stereo/mono switch and 2 octal sockets that can power a preamp but if you connect a meter on pin #1 you can measure the EL34 bias voltage. Here is a photo with the cage removed from the chassis. As you can see, the 4 large outer tubes are EL34’s the ...
