I have a Rotel RB990BX power amp with both channel outputs sitting at -61V. The voltage across the main reservoir caps is +- 66V.
I have in circuit tested all output devices, the driver tranny and the 1N4003 diodes that sit between the output and voltage rails and all these components check out okay. The Emitter resistors and Rail fuses also check out fine.
Any ideas what could be blown, resulting in the negative Vout?
