Last weekend at the Mena swapfest I bought a military transistor testet
Model TT-22 made by Abbey Electronics, L.I. NY in 1968. It uses four
Eveready Alkaline 1/2 D cells N0. E94 1.5 volts. I've never seen or heard
of these runts before I got this thing. Google isn't much help. Any tips
or help appreciated.
