Description
From the sellerI replaced all the resistors and capacitors with new. I don’t have every type of vacuum tube this tester is capable of testing, so I can’t guarantee it works in all cases. I can say I tested a number of tubes and compared the results with a Hickok TV-7 A/U tester and the results matched closely. Tester includes build manual. Condition of the unit face is good. I consider the condition of the case as fair. Selling as is.
