Hi.
So what you're saying is, even if the resistances aren't equal, the voltages can be. I guess that's all that matters. I assume that if the resistances are different, than the half with the greater resistance will produce a higher voltage,
. . . and another assumption: the off-balance voltages would create additional noise to filter out in the d.c. component.
Another item about the phase relationship-thing is in my 39-6, I notice that for some reason, they ground one side of the filiament voltage winding. I thought this may add additional importance to preserving the original phase relationship of the secondaries.
This printed resistance on Philco schematics has already led me down an erroneous path with the IF transformer I botched. Maybe I should stop paying so much attention to those winding resistances.
