HP8566B

Boss asked me to work magic on our 2 broken HP8566B spectrum analyzers. Man what a work of art inside. A good one to own.
One fixed but the other may become a queen. Anybody out there ever been under the hood of this work of art? Our soon to be crowned queen has an interesting fault that locks it up depending on information keyed in from the front panel. Has a problem making it through cal with internal 100 MHz source.

no 8566b at my house this time both repaired and ready to go out for calibration. What a beautiful machine.

I own an HP 8558B  with the 853A digital storage display. It has a problem with frequency stability. The zero marker wonders to the point I can't calibrate using the internal standard.

I'm looking for somebody to fix this and put my spectrum analyzer back on line. Are you interested?

Take every board out and clean contacts with deoxit. Every pot tweek back and forth a bit. I bet it fixes the problem. I'm booked right now for home projects. but sure wanted one of those 8566 units to follow me home.
