Hi again TTech,

I notice that the color coding of the transformer lead wires has been lost?

Since a resistance measurement can differentiate between the primary and secondary the only "difficulty" that can arise is that the start/finish of each of the windings has been lost. That may seem unimportant and in truth may not be in this radio. What can happen is the transformer can pass the phase of the signal without change or invert the phase. Further, an alteration of the phase not as designed could result in the audio stages oscillating. The solution is to exchange one pair of wires from either the primary or secondary on one of the transformers.
