[time-nuts] Temex rubidium

[wa1zms at att.net]

I have a Temex LPFRS rubidium standard that from
all indications appears to have an internal xtal osc
that has drifted beyond what the control loop can
correct for.

Before I take the unit apart to try and manually trim
the XO, does anyone has an internal schematic for it?
(I have the operation/user manual already.)

Has anyone else done this type of repair on such a model?

Thanks in advance,
