RE: quick question Tre'

I have no idea about that. That could be a separate problem.

The heater winding just powers the heaters in the tubes.

You said you got only 3.3vac hooked up the right way?

Try it without the resistors and measure what you get.

I really do think there is a problem with the heater winding of the power transformer.

BTW In a in-directly heated tube, like the 6550, they are called heaters, not filaments. We all say filaments even when we know better.
