David,

What is a good insulated screwdriver to adjust the RF transformers and BFO
neutralizing trimmer? 
--------------------------------------

In the old days boys knew how to hold a screw driver without getting bit.
Its not the insulation between the blade and receiver that counts its the 
insulation between the blade and operator that counts. (;>

We would turn the power off and work the offending adjustment over with a 
real screw driver and get it free. Then with the power on we could get it 
adjusted with a wood stick. The sticks were called orange sticks. They looked like a 
round dowel to me. You keep them trimmed with your TL29. Tool Lineman 29 is a 
pocket knife to some. With a lot of work it could become sharp and less 
dangerous that as issued.

I liked to sand mine to shape on the grinder. The wood stick that is.
