EUREKA!!! The last tube tester you will ever need!! Bring on the pile of 6L6, 12AX7, and 6SN7 tubes. Hey, it doesn't say it can't handle them ;-)

Anyone into 20's battery sets AND keeps them alive could certainly use one of the Jefferson Tube Rejuvenators.

I have one...

I figured someone would :) Some cold and snowy evening I may restore it, at least cosmetically. Finally got a moment to weed through my spreadsheet ... re-discovered this little critter

There is practically nothing inside, transformer, connections, it should work O.K.

I sold one here on ARF a few years ago that I had used to rejuvenate several tubes and it worked fine without me having to tamper with it. It's a good little device and as Chas stated, it probably needs nothing done to it. It just "cooks" the filament to bring Thorium to the surface.
