I've got a Home from 1997, which had been stored for most of that time. I got it out. Sounds pretty good. But I figured swapping out the caps and resistors for top quality parts might be a good thing, given their age. Contacted HeadRoom about upgrade, but none left and they don't do parts replacements (I guess if I sent it in for repair I'd get back stock parts) as upgrade. Mike Olson explained how to get it open. But before going off on a wild goose chase, has anyone replaced the caps and resistors in HeadRoom amps with better parts? And did the amp end up sounding any better?
