Not specifically a Marantz question, though in this case it is in a 2245.
Getting a steady, high, static-y sounding noise in R ch. Subtle. It's in the preamp section; separate that out, no noise.
Noisy 2SA493 or 2SC1000 transistor on the P400?
Question: Is hfe matching a tone board factor, or can I simply replace the transistors? Or might this noise be a something else?
Thanks.
