Re: HP 3456A Repair help needed
As an observation:
Any time the presence or absence of a measurement probe (scope, meter, etc) makes a difference, you're dealing with a marginal situation.
Your probe represents at least a

Re: HP 8640B stiff main tuning
Roy is right.
In many greases, one of the major heavy components is soap. Look at what
happens when soap residue hardens. But, be careful; not all soaps dissolve
in water. Meths can sometimes help.
