Up for bids is a lot of (3) 12AU7/ECC82 Twin Triodes by Mullard. The tubes are used-they are 9-pin miniature types from the early 1950's. They test OK on my B & K dynamic tester and they show no shorts.
This is a used un tested device, plugged in it does work, but I don't have the expertise on how to test it. The machine appears to be in good condition, the case does show signs of wear, refer to pictures for more details.
A true flash back piece great for any man cave or office decor. Rare find B & K Model 440 CRT Vacuum Tube Tester in original case with paper work. Had no way to test it, but it is unique!!!!!!!!!!!!!!!!!
