41-280 Audio Output Wiring - Edisla - 07-18-2015

Is it common for these push-pull sections to have the actual wiring reversed from the schematic?

So if you look at the schematic the Black and Black/White wires go to the lower tube. Mine has the White and Blk/Wht wires going to the top tube.

Looks like factory runs and solder before I got in there.

Thoughts?

My thoughts, not to worry, it makes no difference.

I think it is not important.

The only thing I can think of is if the set has negative feedback wrapped around the output stage it may make a difference. I would leave it the way it was factory wired.

Supposedly there were color standards for chassis wiring in those days, but each of the pre-war Philcos I've worked on goes its own way.

Agree, if you have wo radios playing in the same room and they are not in the same "phase" it will sound strange as when you mis wire a set of stereo speakers. Actually, nobody woried about this way back then, so that's the story as I know it.
