After having a clock failure on OMNI VI+, the trimmer cap for the clock
crystal was adjusted and the clock function was restored, but accuracy was
lacking. It had always been spot on.
Thinking now the trimmer did not age out of tolerance, the crystal did.
Ordered a replacement from Mouser which was installed from the top side of the
logic board without having to remove the logic board for the job.
So far it is keeping perfect time. Mouser 520-ECS327-6-13-X. The trimmer does
not change the crystal frequency, it matches circuit impedance.
