My 41-255 has a replacement output transformer also. Most Philcos of this era that have Push Pull output used the "screen grid resistor tap" method to get the inverted signal needed for the other tube in the Push Pull pair. Most of the 1941 sets used the '41 pentode, which is electrically the same as a 6K6. The B+ on these sets was only about 180V. I don't know why this was the case, because 250V is more common for tubes of this vintage.

One other thing is to check the outputs for shorts, especially that tube for which the leg of the output transformer primary leg was open. especially in a class A circuit, but possibly in Calls AB, the quiescent (no signal) plate current is relatively high. If the plate circuit opens, then the total cathode current is absorbed by the screen, which will overheat to the point of incandescence, burn up and short to either the grid, suppressor or plate, further damaging circuit components.
