:Hello, I have a Precision Series 920 tube tester which I inherited from my father. The unit seems to function well, after replacing the #80 diode. Unfortunately I cannot go any further because the NE-32 neon glow lamp is physically broken and I cannot locate a source for a replacement. Does any know where I can get one? Thanks for any help. 73...Bob
Just do a search for NE-32, they are expensive but available.
