Hi John

There is no color code for the original output transformer in the schematic. You'll just have to experiment with the output wires; as you are getting regenerative feedback now, try reversing the outer leads of the output transformer secondary. But first, as Terry said, use an ohmmeter to find the center tap of the secondary. That is the lead that feeds back to the bottom of the volume control, and the wiper arm of the tone control.
