There's a guy in Bethlehem PA selling a Dynaco ST70. At least he was last week. If you're interested, PM me and I'll give you the details. I was considering it, but went with a new Jolida 502BRC which I'm burning in right now. Plenty powerful for my Salk Songtowers. I'm considering Penta Labs KT88SC's as upgrade to the stock KT88's amp came with.
