Hey Saratoga,
I have owned the accuphase t100, c200 & p300 equipment for many years. I bought it new in 1976 LOL and have had no issues with them until recently when my amp dropped out when some ecaps drifted and a couple of power transistors blew I corrected the problems with the amp its performing well, at the same time I when into the preamp and recapped it to and found a few transistors that were bad and some resistors that were rotted so in a way it was needed. Why I'm contacting you is even though I have owed this equipment from new I have a question as to one of the characteristics of this set up. I would like to know if its the same for all c200s so if you still have this fine piece of audio equipment let me know and I will explain what I'm experiencing with mine under certain input conditions to which I never thought of doing until I made some repairs and put it through its paces.
Regards, MG
