Espey 105 Dynamic Mutual Conductance WWII military tube tester, tested in partial working condition, compare my start price with the other Espey 105 testers posted. The meter needle will line up with the "Line Adj." mark and this will test tubes.

What I have here is an antique Jackson Model 658 tube tester, made for testing old vacuum tubes in old tube radios and tvs. The control panel, knobs, buttons, and guage are all in excellent condition. The exterior case however is very rough and beat up, an eyesore really, as you can see in the pictures.

Honestly, I do not think (in your lifetime), you will ever find a more Beautiful, Iconic, Rare and WORKING piece of equipment! Look at the pictures and look at the thumb wheel for the roll chart, there is ZERO wear; the whole tester looks like it was never used, or maybe once or twice. This testers condition deserved some electrical restoration to get it back to working condition, so I did that for.
