Hello all,
I have a transformer for a GT120 build that I have a quick question about. Both wires for the bias supply winding are the same color. Does it matter what wire I ground or do I have to pay attention to polarity? If I do have to determine polarity, is there a quick way of doing so?
thanks,

Shouldn't matter, but if this is a half-wave rectifier, be especially careful where the ground connects.
Not "polarity" if AC.
Measure continuity between those wires and all others; if no continuity so fully floating, they can be freely interchanged.

Here red wires are input (AC) side.
The other side is obviously AC out at a different voltage, go by your circuit requirement.

Really you should have posted GT120 schematic and transformer image showing wires, labels and colours.
Not sure what "red wires" means, I never saw a transformer image or picture or datasheet.
