At this point at this age they really need a bit of servicing. The big issue with older amps is usually capacitors but all of the parts need to be checked to make sure they are operating within spec and rebiasing needs to be done (even on transistors. It might be expensive but it is the right thing to do do
Vintage McIntosh Question
I have a C35 pre-amp & MC7270 Amp I bought new about 25 years ago. I've updated & upgraded my system & was wondering if having a Mac service center go over them would improve the sound.
The rest of my system consists of an Oppo BDP-95 Blue ray, Focal 1038BE speakers, & Morrow Audio MA3 I/C's & SP3 speaker wires.
