[Elecraft] OT- Old Tek counter calibration

[Brian Alsop]

Guys,

I've tried searching everywhere I can think of.
Manuals seem to have evaporated.

Even tried posting to the TEK forums.

No answer on how to calibrate the master oscillator in a TEKTRONIX CFC250.

Anybody out there with this knowledge?
Even a partial schematic of the area of interest would be helpful.

Yeah, its an old counter...
