Adcom 535L upgrades?


I have an old Adcom 535L amp (60wpc) from the 1990s. It's a utility amp and actually sounds decent if a bit grainy in the mids and highs. I'm not going to try to sell it, as it doesn't promise much on the used market. 

I'm wondering if anyone has replaced caps or other key parts in their older Adcom gear and if so whether (a) it made a real difference and (b) how much it cost? 

Thanks.

those amps usually seemed to have a gritty upper end. was pretty easy fix though. Add some film bypasses to the main filter caps. will cost you about 8 bucks worth of parts if you can  DIY it. Years ago, I used to do upgrades on those earlier Adcoms. The 555 was more work. Adcom put those shiny chrome plated buss bars in the amp to fool some. But the sounded thin and bright. Best thing to do was replace them with solid copper buss bars. Made an amazing improvement.
