    Can't find this online.

    It is on the Fender web site schematic collection, listed as FM65r. They didn't always spell out the "frontman" part.

        Okay so this thing has 40vDC on the output. I've narrowed it down a bit here but not sure what to do.

        Q7 and Q9 are off. I know this because there is no voltage drop across Q7's R76, D19, and R78. There is no voltage drop across Q9's R80. Q8 is on as there is ~10vDC across R79. Q6 is on as there are v-drops across D18/20/21. R76, D19, R80, R78 are all good. There is no voltage drop across the diode string D24/25/26 also indicating that Q9 is off. So Q7 and Q9 are off but their diode junctions test good. If not for this forum I'd just replace 1 or both and see if that fixes it, but thought I'd see what yall think.

            Glad you got it fixed.
