ALM:
Thanks Dylan!  You never can tell if you've come across anything that might prove to be a treasure.  With the unusual glass-shapes and the "innards" of some of these, perhaps so!

I appreciate the insight.

ALM:
How does one go about testing the viability of tubes?

Bob Masters:
Hey Tony !
I don't know how to check tubes with a multimeter, but something you might keep in-mind: Years ago, portable "Tube testers" about suitcase sized were available and a friend of mine bought two of them at auction for $5 each. I know they cost more now, but you might keep your eyes peeled if this is something you might be interested in dealing in for future ventures.

My friends tube testers still work today and check an enormous variety of tubes.

Otherwise I would venture to say that different tubes involve the testing of different combinations of the pins, and for a variety of values since tubes can have a variety of purposes.

Remember the old tube testing stations that many drug stores and hardware stores had ?
Where did they all go ?............
