Yes, this is a tube deck.

If I'm understanding this correctly - I have two secondary windings. One has very little resistance and transmits a higher voltage to the heaters to warm the tubes. The other has a high resistance and drops the voltage significantly before it goes through the rectifier diode and grids.

Or am I completely off the mark on this?
