Heathkit Mutual Conductance Tube Tester TT-1
Price: US $213.00
This tube tester worked the last time I used it 10 years ago. I haven\'t tested it recently because I have no tubes of a known condition to check. It turns on and the lights light, as the pictures show. I make noguarantees regarding the operational condition, but I have no reason to think it won\'t work. Manuals and extra tube charts as shown.
