So this is a follow-up. The audiogon seller had 2 B-2s for sale. I got one and Walk&Talk got one.
After SpecialIdiot was gracious enough to tell us the trials and tribulations of his B-2 amp that he won on ebay, which was DOA/damaged in shipping, I found out that the amp I just purchased was the same amp.:sigh:
The seller was up front about the repairs (after I called him on it. It was not mentioned in the ad). He stated the back of the amp was bent in, and it broke 2 pieces of the protection board.
The seller bent the rear panel back and then used scrap PCB board pieces and glued them to the OEM board for support.

Apparently no traces were broken. He got it working again, and resold it to me.:grumpy:
I received the amp (it shipped before I found out about its true history), and without opening the box or testing it, I sent it back. I did get a refund today (minus $50 in shipping), which was helped along by the dispute process of AG.
I tried to give him a fair offer for it as a parts amp, and have him refund $150 of my $425 payment, but he didn't want to do that. Actually he wouldn't consider a return until AG got involved.:bash:
This is a warning that there is a B-2 out there in San Jose area (with a flaky Speaker A switch) that may be back on the market soon. Caveat Emptor!! While it may be working, and be a decent parts amp, one of the main boards has been broken and glued!
Also, the amp was single-boxed (not the OEM boxing), and I have no idea if the amp made it to my house in one piece or back in one piece, as I didn't remove it for inspection. So, poor packaging as well.:nono::nono:
