Why not draw the schematic yourself, doesn't look that complicated.
All ou need is the connections of the IC.

Two reasons,,, I'm not familiar with IC gear, chips etc,,, and would really like to see how it was intended to be wired for unbalanced audio amp use... I used it with a couple of tube amps, a Maggy 175 clone,,, and a 6BG6 SE amp I built and it sounds very good, almost matching the RCA tube phono pre I built, in an A-B switch comparison... however, I tried it with the 811 SE amp in my avatar and it started to motorboat... I'm not sure if its over driving the 811 amp, or the trim pots aren't adjusted to match it,, figured an original design schem would explain how to set it up... And would have design voltages on it...
I appreciate your interest, I'm hoping a FM broadcast station tech that remembers these may shed some light...
