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
