[R-390] VFO / BFO with no ballast.

[Tom Norris]

Now to get a decent freq counter that I can synch to my GPS standard
and check the drift with and without. Not sure it is worth the trouble
though, I doubt if I can find any difference. Be neat the lock the
crystal oscillators in the thing to the 10 mhz standard though.. hmmm.

But, Bob and group, I've notice no discernable differences with jumpers
and 12BA6's or with a resistor. I think the main thing is that the ballast
was indeed designed to compensate for the variety of mains voltages
the radio was likely to encounter in the field and with reasonably stable
home AC power, it is not likely to be of much use.
