[TenTec] Omni VI 20 MHz crystal oscillator

[Ken Brown]

Anyone know the capacitance range of C31, the trimmer capacitor for the 
20 MHz ovenized crystal oscillator on the LOGIC BOARD in an Omni VI? 
Yes, I know about the TCXO modification. The problem on mine seems to be 
that the trimmer is flaky. I want to replace the trimmer, not convert to 
the TCXO.
