I have this amp under work and the +/- 45V fuses have blown. I also found a
schematic for a AU7900 amp, which seems to be almost the same, however the
scan is so poor that I cannot make out the values of resistors R72 and R71
on the main amp PCB.

So if you have a schematic, or if you know the values for these resistors,
let me know.
