OCXO for HP 53xx Series

[VK2RK]

I have designed a replacement OCXO for the HP5384A, 5385A, and 5386A
My approach differs from some, the use of standard components to keep the cost low aside from a constant voltage reference.

The design offers a fine frequency adjuster that resides at the rear panel provided oscillator adjust hole.
PCB are available as are complete Oscillator
