I got this tempest the other day. It was mostly dead. After some work on the monitor, and board I got video and can play a game. The beam current is a little high. I just ordered q900-904 to limt the beam current to where it should be. That should take care of that.
Anways. Back to the sound. No sound at all. I turn up the volumn pot and there is an audible hum. I have already verified voltages on the Ar. Where do I go next. I have never had a problem with Tempest sound before so.... kinda at a loss.
