[volt-nuts] HP419A Meter Pegged to Right

[Stan Katz]

That clinches it. Brooke's Tek tour reminded me that I have on file a
"Service Scope" from Tek entitled "Washing Your Tektronix Equipment". I can
follow those instructions less the drying for 24 hours in an oven at 125F.
Doing so will probably have me kicked out of the house by the wife. A hair
dryer will have to suffice.

The use of a dishwasher, which I could pull off without being found out by
my spouse, does require removing all the pots. Anyway, I think that
dishwashing is most appropriate for boards with all surface mount chips.
Forty year old electrolytics (all of which surprisingly have tested good)
might balk at being machine washed.
