Shadorne...thx for the reply...The C200 before the BG upgrade was "normal" 10 o'clock. My tech did the recap and cleaned everything...pots,PCB connections...ect. The only thing I can think is my VAC 140's are burning in and with about 50 more hours maybe things will normalise. The Nichicon Muse C200 didn't change that much but the BG so far has popped a good deal. I experienced some gain pop when I replaced the coupling caps in my dac...Wimas to Mundorf M-supremes...interesting.
Gain Pop....causes??
I have had several Accuphase C200 preamps...my experience is my normal listening level on the volume control is 10 o'clock or 10:30...this has been the same with 3 different C200's. I have used the same amps. I have had 2 preamps upgraded and recapped...a nichicon version the gain dropped a little to about 9:30...but a Black gate version dropped all the way down to 8:30...now 10:00 would blow me out of the room. Has anybody experienced this with cap upgrades?
