Great work, you are the first tech that actually tested for other resisters and capacitors in the in the circuit and found problems and also found differences in the schematics as well. I am impressed. Thank you. Tom Cowan Digby Nova Scotia, Canada.

I have been a Fender amp player for 57+ years ... I always wondered why techs did not naturally look on down the circuit for problems. If a part fails, does it not seem logical that more down the line will catch that failure and fail as well? Maybe I am just one who knows a little, which can be dangerous, I guess ... BTW: Can you repair hearing systems to rid tinnitus?

BTW, those phase inverter resistor values are correct, the schematic is incorrect. The AB763 schematic you are using is the early one, which was later corrected. The tip off is the two 100k plate resistors on the phase inverter, they should read 100k & 82k to balance the phase inverter. Look for the later schematic.

All the voltages are going to be off if that amp is run at wall voltage, and then compounded if the two dropping resistors between the filter caps are as badly drifted as those two were.

Very thorough, Jordan. This vid is a great teaching tool. Your Navy portrait looks familiar. Were you an AT or ET? Serve during 68-72 perhaps?

Don't you think that voltage drop can come from the choke?

Not unless somethign was terribly wrong with it, sis you measure the resistance of the choke

Hi, good morning, I greet you from Nicaragua, I just wanted to know if you can give me that diagram of the amplified guitar that shows in the video since I have one and I need the dator to repair it, I would really appreciate it. Thanks in advance.

I have a non working silver face . Do you work on these and where in the country are you ? Do you have an email you would like share
