Inside an Isotemp OCXO107-10 Oven Controlled Crystal Oscillator

interesting teardown, thanks.

for homelab application where extra space & power consumption is not a real concern, "temperature resistance" (tempco) is no longer relevant. you can get a constant temperature controller with +/- 0.01 degree range kind of spec for $65. verified using a reputable digital temperature sensor (outside the control loop) and the performance is pretty solid.
