Hello guys, does anyone have used working 80hz oscillator for sale? Thanks

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.

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.
