You are bidding on a pair of Western Electric type 101D tennis ballshaped radio/audio tubes. They test goodon my Amplitrex AT1000 tester, as one shows emission, Em, of 93% and Gm, grid emission, of 90%, ofspecs, and the other tests at 122% Em and 90% Gm, both with minimal gas. So, they are good strong usable tubes with strong matched grid emission. The Amplitrex uses 4.5 volts on thefilament for testing these. The internal glass arbors are ingood condition with ...no cracks or breaks. These are a later version of this style tube, witha black bakelite bases, and gettering on one side of the envelopes. The designation is embossed on the envelopes. They still retain the gold tips on the end ofthe pins for positive electrical contact. They came from the same WE audio item, so have always been used together as a pair. They are nice strong, usable tubes for your amp, and are guaranteed asdescribed. Shipping weight is 2 pounds, well packed. Please see my otherauctions for more interesting tubes and audio items.
