I do have *some* excuse for not getting more done in the past couple of weeks, starting with four kids and a fairly challenging job. But, anyway... I removed the 5 selenium rectifier stacks tonight

HI Casey, You really need a manual. The first place to check is the power supplies to make sure they are working correctly. The manual will tell you the test poinst, how to check them, and what to

First thing I would try is a new CRT . . . Stan w7ni@...
