Well, checking grounds around the coils and trimmers, they all seem good. Wonder if I could have a bum replacement tube in there. Still don't know why the grid leak voltage drops out when I turn the tuning cap to the low end of the dial. The oscillator can't be running with no bias can it? I also seem to remember reading that the 6j8 can be a finicky oscillator, but there doesn't seem to be any alternate replacement for it. The one in there is one I ordered as nos. Don't know where to go from here. Maybe try re-aligning it. Ed
