DAYRAD 381 Schematics and/or setup data

Post by homebrew on Tue Apr 19, 2011 7:34 am

I purchased a pretty rough DAYRAD model 381 tube tester on ebay. It has a control missing and there are 2 clipped wires underneath. I would guess this is the line adjust pot. I need a schematic to verify this and get the value. A general wring out seems to show that the transformer and resistors are good. This has alot of features for just an emissions tester, so getting it going would be very useful. Thanks in advance
