I have not found a schematic for the Paul Model 205. From what I see on the web most have the Model 201 without the power transformer and different tubes.
Tube compliment for the Model 205 is 5Y3GT, only one 6V6GT and two 12ax7a’s.
This unit has 4 jacks, three pots (Tremolo, Volume and Tone).
I think one of the 12AX7A’s is used for the Tremolo circuit, not sure.
I will try to trace out the circuit and compare it to some of the Fender Amps.
What I found so far:
This Amp only has an older 2 wire power cord.
Should I use a newer 2 wire cord for polarity or use a 3 wire cord, will the 3 wire cause more hum?
Not sure what caused the failure but the lamp is open (Fuse holder is missing) and it looks like a small amount of liquid was on the 6V6GT tube (Stain on the tube). Will test the tubes next.
Is it ok to use a Varic at low voltage without tubes to check the power transformer outputs?
