I've got it all buttoned up now. Hammond 290AX PT and Hammond 1750H OT. A 1963 Tung-Sol 7025 in V1, an RCA 12AU7 mil-spec (5814A) short black plates in V2, a Tungsram ECC83 in V3, a JJ ECC83 in V4, a pair of 1950's Sylvania gray glass 6V6GT's in V5-6 (one labeled Philco, one labeled FoMoCo), and a 1962 RCA 5U4GB in V7. I ended up biasing it at around 18 and 20mA plate current for the pair of 6V6GT's at around 399 volts. Sounds great! (and the noise floor is very, very low).
