I tried a new 3rd IF no change. it does not have a shield over the 3 IF, and the tube socket did not seem to have a ground contract, so I assume that is correct. Put one on it anyway, no change. I did not try 1st or 2nd IF tubes yet. Will give that a try, if that does not do it I will just call it ok for now. Oh also tried the video amp (6GH8) with a couple others inclding a 6EA8, it has a shield which was in place, again no change.
