[sdiy] Ovens for oscillators?

[Glen]

Hi everyone,

I know that some precision quartz crystal oscillators use ovens to keep the
circuitry's temperature elevated above room temperature by several degrees.
The exact temperature of the oven is closely regulated, to prevent
temperature drift affecting the components. 

Now I know that this sounds like an extreme measure to suggest for
home-built synth oscillators, but has anyone tried it? Would it eliminate
the need for special tempco resistors? I realize that if the oven's power
failed, the oscillator might indeed need recalibration afterward, or at
least a long warm up time before use. Unless special mobile power sources
were employed, it would make the synth less mobile, and probably not suited
for taking to a live gig. However, for an experimental synth that always
stayed in one location, and always supplied power to the ovens, might it be
useful?

Later,
Glen
