Welcome aboard, Ben! Sorry to be late to the party, but I just got back from vacation. I am in total agreement with Brian (B-Man) - there are some great techs HERE, but most of us do have "Day jobs", and we do this as a hobby. If you have a little bit of patience, we can really inprove some of your vintage Carver gear.
I am a home theater buff myself, and like you, I take pride in the ambiance of my HT, as well as the performance:-)
Nicely done!!
