An typical telescope drive corrector schematic from the 1980’s
An typical drive corrector schematic from the 1980’s showing the frequency source (a LM555 based oscillator), a bit of logic, then the power transistor and transformer setup used to create an AC signal.
Do you by any chance know where I can obtain a schematic for an Accutrack 2117?
Thanks, Mike

Not a clue. I would check on one of the astronomy bulletin boards like Cloudy Nights, a lot of knowledge there. Otherwise the basic schematic is probably much like the one I posted here, probably the same drive transistors and transformer, with perhaps more bells and whistles in the control stage.
