Just wanted to share that I recently did some modifications on an MP20 for a client. He wanted to swap a Lundahl trafo on the other channel and asked if I saw anything else that'd need attention.
So I looked at the schematic and there it was.
A damned balancing driver/receiver combo on the signal path that always does its thing even if the inserts are not in use. :shock: :?
I asked and the guy said he never uses the inserts, so off I solder the SMD op-amp, cut a trace or two, run a couple of wires and things are much cleaner now.
What's the point in making a TwinServo (?) amp when you toss a crappy balanced driver/receiver in the signal path, all the time? Why the hell would you need inserts anyway when you could toss your compressor at the output? Why does this thing have a "mixer" in it, I see very little sense in having a 2-channel mixer with panpots in a 2-channel preamp.
:grin:
