He and I have been emailing. I made a strong enough case (I sent him pics of my 2000S PT, along with a 200S) that he suspects things aren't kosher and he's going back to the techs that put it together. He seems like a good guy, he just doesn't know much about amps.
He pulled the auction until he gets it straightened out. I told him he should split; he'd get $800 or more for that cab, I bet, there are lots of 2000S heads out there by comparison. The amp might bring $750, or it might bring $350, you never know about that, but he'll do better splitting.
Nobody makes a PT for that except maybe Mercury, and that would cost you several internal organs. You might find one on eBay now and then, the Dynaco Mark VI is I think the hifi equivalent.
