I have a 2238B, paired with an old pair of re-foamed Snells, which sounds fantastic. I'm on the lookout for a 2285B, but I'm afraid they're way overpriced at this point - I've seen them for as high as $2,500.00, but most tend to sell in the $1K range.
These old Marantz receivers from the 70s are hard to beat once they've been recapped and fully serviced.
I see your Q102 sign. Remember the Zoo?
