[R-390] antenna trim repair

Au contraire, Dave.  Your question sparked some lively discussion in an
otherwise very quiet list, which is usually the case during the summer
doldrums.
No doubt you had several members scurrying off to look at that pin in their
tuning caps.

I did, EAC serial # 6170.  The pin looks like a roll pin, with a flare on
one end so it can only be driven out in one direction.  You need an
appropriately sized roll pin punch which has a dimple on the business end
of the punch to keep it centered and not damage the pin.  Roll pin punches
are used extensively in gunsmithing.  Sometimes they are referred to as
spring pin punches.

So, don't give up, let us know if you find a solution to the intermittent.
Did you try bathing the control in IPA?  Maybe its just dirty with oil or
grime.
