This was my dad’s tube tester. He was really into audio and electrical stuff but he’s passed.

Priced to sell! Ships SAME DAY! NO BS. NO WAITING. NO GAMES!

Comes with instruction manual and 2 tube data booklets that show you where to set the levers and knobs for each individual tube

I tested this on 6 different tubes I had and I got good readings on all but 1 so it does work
