Repairing a Telecom AV-830 switching power supply (or maybe upgrading it)

I have an auxiliary Telecom AV-830 switching power supply I use from time to time. Recently while testing a circuit with it, the power supply explodes. The internal fuse was disintegrated and the main ICP was activated. That usually means something very bad is happening with the power supply.

A 10MHz TXCO master oscillator

The heart of any transverter system is the local oscillator. In practice, a transverter is as good as its local oscillator is. For my transverter project I choose a Toyocom TCO-291L2 oscillator I rescued from a UMTS board I have from surplus.

After spending a lot of evenings looking for its datasheet, I could not find it. I found the datasheet from other TCO-291 oscillators, but nothing from the TCO-291L2. Maybe it is a custom device, o maybe it is discontinued.
