oscillator
I have what appears to be a temperature stabilized oscillator made by
CTS knights inc Sandwich IL Ithas an octal base appears to take two crystals Part# 900-0196. This is about all I know about it. Any other info would be appreciated. Jimmie |

There is a pretty good chance it was from a Lo band VHF unit. Jimmie |

Any other info would be appreciated. Jimmie You sure it's actually an oscillator? I have some units that could be like you describe that are just thermostat-controlled ovens for crystals. The oscillator is separate, for the ones I have. Guess you could find out mo check the resistance between each crystal-socket pin and each of the octal base pins (and perhaps if two of the crystal pins are in parallel, sharing a common ground or equivalent).

Cheers, Tom Thanks Tom. You are correct. Leads from the crystal sockets go directly to the octal connector. Jimmie |
