Default Re: Assessing the 'Quality' of AF output transformers

Could you take two single ended ones, remove the I laminations, slap them together E to E and get a half decent PP transformer. No need for the gap and hence more inductance and pseudo interleaved windings.

You could, BUT it would make a woeful transformer!!
I dont know if you have vere pulled a "C section" transformer apart, but the two "ends" of the laminations are polished to mirror smoothness to eliminate leakage.
If you wanted to polish the ends of the laminations so they fitted perfectly together it might work.
Magnetic flux is sort of identical to electron flow, so imagine water in a pipe. Your two single ended transformers connected together ( butt joined, NOT interleaved as almost all transformers designed for PP operation are) would be similar to a high pressure pipeline joined without being soldered together. In other words the flux would be running out like water at the joint. So, inductance would be horrible, and would get worse with decreasing frequency.
