It is a sand coated resistor. There is no markings on it, but think it is working for the moment as it does get warm. As soon as I can get a Sams, I will replace it and the other sand resistor.

I have made SOME progress. First, my 75/300transformr was bad. Trying another one gave me sound, but the volume control is not working. It looks like someone has tinkered with that section also.

There is a electrolytic cap in parallel with an 8 ohm power resistor coming off the 6BQ6 and going to ground. No voltage on the pos side. That my be why I have no high voltage. They both look like replacement units. I need to find out exactly what goes there.
