So my amp tech had 3 mini rectos at his shop with the same problems. the clients complained that, when in the 10W mode, there were severe volume oscilattions, plus at the lead channel the volume was always too low and very bright.
he sent a mail to Mesa about and they replied with the following instructions to fix the problem:
"1) Change R8, the mute timing resistor from a 1M5 to a 560K
2) Change C47, the mute timing cap from a .082 to a .22-- note that the
positive end of the cap points toward the rear of the amp. Also, the new
larger cap can mount into the holes as shown-- it's the same as the original
cap.
3) Add a 1kuf 25V cap to the +16V supply, in parallel with C44"
Looks like we'll be seeing a revision B coming out shortly . . .
