thanks RWwear. Thanks much, I'd already read this link but will indeed go back and glean more (and actually sent a query to Lynn Olsen, if he's still around). In fact, I used to work in retail audio back in the day here in Oregon (home of Audionics of Oregon; we were a dealer for them) and loved the little CC-2s when they came out. It was a sweet little combo paired with Infinity Infinitesmals and a sub. Once I get the caps replaced I too will run them in mono. I'm reliving my vintage days a bit (it's a bit cheaper than moving forward:) ) and also found one of my all time favorites that I used to own from my '80s audio retail days, too, a Robertson Audio 4010, that I would love to find another of to pair with it.
I will most likely get recommendations from the guys at InnerSound repair here in Portland, OR as they have also worked on my two Audionics CC-3 amps (that are prototypes I suspect that I picked up in perfect shape for a great price, complete with original Audionics of Oregon boxes---they have a Fosgate-style faceplate, but seem to be definitely a Bob Sickler design, right before the buy-out. Thanks so much for your helpful reply. What are running yours with in related gear?
