[R-390] Some practicalities on alignment of the R-390A/URR

[David C. Hallam]

What is a good insulated screwdriver to adjust the RF transformers and BFO
neutralizing trimmer?  I've tried the plastic and the fiberglass ones.  The
tips just break off.  I wrapped electrical tape around a long screwdriver to
where all but a little of the tip was exposed, but I haven't found a good
way to insulated a screwdriver for the RF trimmers.  I've gotten bitten
several times.
