I searched for the 8662/3 schematics, but I only found low resolution PDFs.
Even for the 5071A I found a service manual (assembly) but it does not

P.S. BTW, I exactly do not know the characteristics (phase noise) of the
original XTAL oscillator installed on Perseus, so I can't give more details
on my real requirements....
