I have tried a new 12BY7A and 5763 with no change. With the DX100 in CW and
the PLATE switch off...I have to run the DRIVE pot fully CW before the GRID
current shows on the meter. Once peaked with the DRIVER TUNE and set at 5 ma
all is well until I run the DRIVE pot back down CCW. Then running it back up
results in no grid current until I max out the pot again. This will also
occur if I move the DRIVER capacitor off peak. I always have to max out the
DRIVE pot Really screwy HI HI.
