NYC at Julius Futterman’s West Side apartment. His hand-made OTL tube amps remain unequaled today! Starting in the late 50’s with the H1 and H2 triode OTL’s , then in 1964 with the H3 Harvard Music HB5 pentode OTL stereo chassis and finally the H3aa mono 6LF6 OTL’s in 1975. The H3 was the only one to get a mainstream audio mag review by High Fidelity in 1964. In 1976/77 The Audio Critic reviewed the H3aa mono’s and was quite impressed! Julius died in August 1981. Soon afterwards I bought my first pair of H3aa’s (#111A,111B) from a Boston dealer (Q Audio). I used them with the Quad 57’s.
