Does anyone have the test point voltages for this amp as I have ongoing problems with mine

[Enzo]

What problems? What test points?

Solid state amps have high voltage for the power amp = probably in the 35-45v range I'd guess. And the preamp runs on low voltage of 12-15v with positive and negative in both cases.

Thanks for the info Enzo, I'm new to electronics and am feeling my way along. The Fender diagram for the amp shows various numbered test points which I've assumed should be checked in order and show various voltages. Any further help would be appreciated.

Are there not voltages included in the test point labels?

On the parts layout, it just identifies where each point is. On the schematic itself, the TP also has a voltage associated there. Like TP1 is the input with 8mv there of signal. If you input 8mv of test signal there, then the rest of the AC TP voltages should fall more or less into range as specified. Note that AC volts are in round boxes while DC volts are in square boxes.

There is no order to test them in, they are just benchmarks. Use the ones that are relevant to whatever you are doing on a given repair.
