Re: Spring loaded Old Style Front Panel Buttons
Hi Adrian, Okay - I may give that a try. I wonder if there was any grease originally in the mechanisms that has dried up and possibly should be replaced after cleaning? Thanks, Barry - N4BUQ

Re: HP 8640B will not lock
I would suggest that you start with the basics. Check the power supply voltages, noise and ripple. Very likely due to the age, the filter capacitors are weak. Any noise will disrupt the logic in the

Re: Part Needed
A direct plugin solution seems to be difficult. The grounding of MMICs is quite critical and maybe you need to do some surgery on the circuit to connect a daughter board that can be properly grounded
