Powers up, but no tube chart. All tubes power, fuse intact. With calibration ( detailed at diyaudio) this is a nice little tester. $65 plus $30 shipping in lower 48. Charts and book available on ebay $10
Good deal on a decent mutual conductance tester.

Does anyone need this? Price drop to $45 plus shipping. If no one wants it, I'll take it Good Will.
