Vintage “Accurate Instrument” Model 151 Tube Tester with manual and supplement chart. These were used to check the condition of vacuum tubes. The hard case is 10.5“ W x 9“ D x 3.75“ T, has a hinged lid, a leather handle and is in excellent cosmetic condition. It is basically untested as I do not have tubes to test in it but as shown in the last picture when it is plugged in and I turn the dial the needle does bounce from bad to good. $95 cash only. No Venmo or other form of payment. FCFS with no holds or delivery. Porch pick up is in Sherman Illinois.
