Here are a couple of good books:

Frerking, M. E., Crystal Oscillator Design and Temperature Compensation,
Van Nostrand Reinhold Company, 1978.

Parzen, B., Design of Crystal and Other Harmonic Oscillators, Wiley, New
York, 1983

There's another good oscillator design book I borrowed recently, but I
can't recall the details.  I could look it up in a day or so, if you're
interested.  However, I don't recall a lot of oven schematics in these
books.  (The above books do show some of the early microprocessor
controlled TCXO circuits.)

I've got some stuff from Wenzel for building an oven (which I really am
going to get around to doing, one of these days...), including thermistors.
 Seems to me the increased sensitivity would make for a better oven than
trying to use the (relatively) insensitive transistor junctions to measure
the oven temp.  After all, linearity isn't a concern.


Just curious: will you be using an AT or SC-cut overtone rock?
