THis vario goes back to the late '70s and was from Ismail days. The
50S was triple range dual dampening the 50D was dual range (x1 and x.5) dual dampening so the 50H must be just dual range or was it dual dampening?? THere will be one switch down for off with keyway up. The AU-22 (not AV) was the later of the two main audios he did and did not have a mute switch in the middle. One knob was vol and the other was the threashold between the beep beep of lift and continuous sound of sink. The internal speaker was 100ohm and NOT 8ohm etc. ONLY use 100ohm replacement speaker. I hate the sink tone. The audios had 2 cheap unbranded transistors which always fail with time. There were just 1 sheet on each instrument as instruction. THe vario should be Rev15 (or rev 14) for reliability - Rev 13 always would leak. It needs a std winter .45lit flask which goes to "C" and TE goes to "S" Raulf the designer runs a firm called Cambridge Flow Inc I believe in the Boston area. Good luck!!!!
