Hello
I need help !!
the V4 preamp (12ax7) is no longer supplied correctly .... (weak filament)
the reverb no longer works ... and when I put the Graphic Equalizer I lose half the power.
I tried to put a footswitch for the reverb ... would that have destroyed a circuit? the reverb transformer?
apparently I have B: 444v, C: 438v, D: 431v
Has someone already had this problem ?
possible to have a pict of the PCB MESA RP 9C? and PWR 7C ?
i have already the schematic of MK2B i miss just the PCB to find and repair my amp...
someone have it or guide me to find a solution pls ?
many many thanx
