[R-390] power tube removal

[KC8OPP Roger S.]

Tony,

I have a tool here made with the Eimac logo on one
leg, that is called a "Tube Extractor".  Built like
reverse tweezers with notches on outside of each leg
that fits the outer ring of the tubes.  Overall it is
about 5 inches tall, made with 3/16 inch wide strap of
SS.  Squeeze it together and work it through the fins
until the notches snap in place then "Extract" the
tube.  Works great! but only have the one.

Good Luck
Roger
