If I recall there are two xtal oscillators.?
They are both designed along the same lines.? Check the output on a good
digital scope with at least 500 mhz bw.? You will see where the problems
begin,? you will see noise & non linear waveforms.?If there is a
problem here?it will only get worse as you move through the
instrument.? ?I'd find a service manual somewhere before you start the
process.? The attenuators will likley need cleaning as
well.??After you clean them switch the?gold?plated
finger?around,? this will sometimes help.
