RE: Harvard Electronics H-1 OTL Amp

Back in about 1979 Julius made me a direct-drive amp to power my STAX SRX ESL headphones. I don't know if it is one of a kind or not. JF also hand-drew the schematic for me. (You're right, Lew: he was a nice guy.) The combo is still sensational. I will never part with the amp or the schematic. Call me sentimental . . .
