[Hallicrafters] Tube Tester adapters

[TC Dailey]

Rich (not me),

The only ones I've actually made for the B&K 500 were for a couple of full
wave rectifiers.  Figuring that the filaments, cathodes, and plates were
pretty much the same places, I took KNOWN GOOD tubes and then played with
the bias adjustment until I obtained satisfactory readings that looked in
the ball park.  I DO know that some of the adapters have additional
resistors in them to bias them differently, but I have had ZERO LUCK in
finding ANYBODY who is able or willing to supply info on adapters that they
may already have.

There HAS TO BE some info on these, SOMEWHERE!
