It would probably have to come out of an old Tracker. Any luck building a replacement circuit?

no didn't get a chance to put oscillator from ebay.whenever i wanted to put,it started working..lol.and it has been working since last couple of weeks.but looks like i have to bit a bullet and try to put ebay oscillator in.But it would be great if i can find from old oscillator if someone has.

Even if you found an old oscillator I wouldn't trust to work very long.

Shouldn't be too difficult to build one. Back in the 70's I built a 80hz clock circuit that was part of a FAX system,  for receiving slow scan satellite weather pictures using TTL 7400 chips.
Might still have the circuit diagram if needed.

yes that would be great if you can post the schematic.:)

Will let you know soon as I find it,  if I have it after so many years.
But I did find the link above added by Curtis on this forum that shows a circuit for a replacement 80Hz oscillator that was available in the 80's.
Looks quite simple and not many components, so could be easily be put on a piece of Vero board or strip board.
You just have to add a couple of regulators for the +6 & -6 volt supplies.
Hope this helps.
The circuit I built used a crystal oscillator that that was divided down.
