RE: TV-7 tube tester line adjustment problem

Posted by ecir38 on July 3, 2012 at 21:07:26:
Make sure you check your mains voltage first. I was helping a friend diagnose his TT-1 tester over the phone recently and come to find out his house mains had spiked to 128vac and caused his tester to not calibrate or line adjust.

The schematic looks like the tranny wants to see 93v after the line adjust.
