My Carver 4.0 is currently sitting in Oregon about to be rebuilt, also getting "bypass caps" for 60 bucks I figured what the heck, though I have no idea what it is. Roland at Carver Vintage Audio explained it and like an idiot I pretended to know what he was saying. Basically, he said it makes a noticable difference so I got it.
anyone have a clue what this is? either way I know I'm gonna get a great amp back. No qualms putting the $ into it as this has been my favorite amp for a LONG time (bought in 04?)
