Jim,
Thanks for following up on this. The thermoswitch that I'm looking for
closes on reaching a trip temperature of 78C. The original unit was
made by Princo. I wonder if your friend could tell me if he has any
leads on a 78C thermoswitch.
Thanks again,
Russ

Today I visited a friend who collects all sorts of old electronics and
asked him
about mercury thermometer sensors. Turns out he had several from
various GR
pieces of equipment. Some are in a straight shape with "trip"
temperatures of
50 or 60 degrees C. One is at a 90 degree angle with a 60 degree C
trip point.
I'm sure it is a very long shot but I wondered if any of these might
work for
the frequency standard you are rebuilding.
Most of the above temperature sensors were built by "Precision". I
have the
part numbers.
What do you think? Does it sound like any of these could be
replacements for
your unit?
Regards,
Jim
