For the DIY-ers, I have a pair of Lundahl LL1620 C-core ( M6 ) output transformers gathering dust at the moment . These are suitable for 300B or 2A3 class-A push pull with 6k A-A load, or PP pentode output stages in local feedback mode ( KT66/77 etc ) . Not suitable for ultralinear, though.
Various configurations acheivable by wiring options : 4, 8 or 16 Ohm output . See Lundahl site for datasheet .
These are currently wired-up for PP 300B but the wires can be unsoldered if you like .
Bought in ~2003 and used for a couple of years. Bought some fancy Bud Purvine ( O-Netics ) outputs with litz-wire secondaries etc, so these got sidelined !
Given these cost about £350/pr new, I'd be looking for something around £190 ovno.
Cheers
