You should have an equal amount of AC on pins 2 and 3 (plates) of the type 84 rectifier with or without the tube plugged in with respect to ground. If that is so, you should have DC of a couple of hundred volts on pin 4 (cathode ) of the type 84 rectifier with the tube plugged in. Then you can plug in the type 41 audio output tube and measure the plate and screen grid voltages as per the schematic. If there is nothing there the field coil on the speaker may be open. Anyway work through the voltage dividers after that.
