Picture is representative of one of the boxes of rectifier tubes; note the tube you receive may or may not be shown in the picture; most likely not given the thousands of tubes we have. The testers we use are Phil Frakes's Bitmatic computerized Cardmatic testers from Tubesontheweb, the specific models are Western Electric KS-15874-L2's which were made for Western Electric by Hickok; we currently own two of these testers.
