Question About Hughes & Kettner Musical Instrument Amplifier ATTAX 100
Huges & Kettner Attax 100 Amp head...

I am a service tech, and need a schematic to repair a client's amp. I replaced the TO-3 outputs, but the 12AX7 is not firing up. The plate voltage is there, but there is no voltage at R127, the bias trim pot (I assume). Is there any way I can receive a schematic for this head?
