No problem. Just use a diode and filter capacitor and tie it to the
filament line. I've done it. It will work fine.

I didnt have a 6vdc relay in the junk box, used a 12vdc relay instead.
Had to build a half wave doubler to get 13vdc off the filament line but
everything seems to work fine. Thanks for the idea.
