not sure if this tester works, i found it in a collection of old stuff and thought i’d try to sell it for a friend. i’ve noticed they are used by people on diyaudio.com and also some guitar forums. i plugged it in and switched the selectors around, no smoke so it possibly works fine? missing two knobs and the original wood case. manual is included. get yourself a deal?!
shipping from Westby, WI or pickup on the spot is also fine.

It's an emission tester rather than a mutual conductance tester. S0 not super useful, but better than nothing as they say.
