As I am striping the second amp and popping the end bells off for paint, I noticed something again that I just ignored on the first one. Can anyone explain why the output transformers have a different part number from each other on each amp? They are different also in that the laminates are slightly shorter on one than the other.

Will this cause any issues when p parallel the two transformers?

It is just strange.

Thanks!

Blair

according to the schematic they are different part numbers and the schematic does show a difference in the laminate representation.....will it hurt your project...no becuase you are paralleling them and thats how they are on the MO-200A amp. I would leave them mixed matched ....there might be an inductive orientation based reason for the differences due to how close they were installed...

Thanks!

I kind of figured. It just seemed a little odd to me.

That is a really clear schematic! Better than the one I have. Any chance you could email it to me?

Thanks!

I don't see that in the schematic you posted. What exactly is the difference?

Aside from the part ##, if you look, the laminate lines have different spacing. I assume that is it.

Hahaha, no, that's pretty funny though.

The schematic symbols have nothing to do with the physical attributes of ANY electronic device. Just like on a capacitor, if you draw the two lines further apart it doesn't mean the plates of the actual capacitor are further apart.

Well, that's all I see

Other than part #s. the transformers are definitely different though.

makes sense....they used different part numbers and different laminate spacing on the schematic for no reason. I'll measure their inductance during the week and report back.
