[R-390] Another (perhaps) silly ballast question

Many thanks to all the replies concerning ballasts and transformers.  In
case it wasn't apparent, my thinking was if I could find a 120V/60V
transformer (or some other 2/1 ratio xfmr), then connecting one primary and
one secondary lead to ground, connecting the other primary lead to pin 2 of
RT501 and the other secondary lead to pin 7 would provide the 12.6VAC
necessary for the oscillator tubes.  My thinking was that this would be
better than a big old resistor out there dissapating all that heat.

I have a much better plan now, though.  I'm going to implement it and if it
works as I think it will, I'll post the results here.

73 to all,

Barry - N4BUQ (okay, little horsey, I'll leave you alone now...)
