I have a Hafler P125 that is getting input signal and AC current, but the outputs are dead. I know this isn't a guitar amp specifically, but I'm hoping someone here might be able to help.
I can't seem to find any specs, schematics, etc. anywhere online. I was hoping the Hafler site would avail me, but alas, models this old are apparently of little concern to them.

Re: Hafler P125
contact hafler ask for a schematic if they wont give/sell you one ask for the local service center call them and ask if you can purchase a copy of the output section. since you already have the unit and the parts are stock unless you are testing for voltage the schematic isn't needed.
Start with looking at the PCB for signs of burning. if you have input and no output start with the output and trace back until you have signal.
the fuse is good? internal fuse?
probably a blown transistor or if it has one transformer. the burn marks/ bubbles and browning on parts will be a huge clue.
contact hafler service first they may have a flat rate for the repair that is cheaper then doing it yourself.
