Years ago, Mike made mention of someday rewinding a particular 'Q' series transformer (can no longer recall the number...268?/265?).
This transformer was so difficult to wind he said that if he pulled it off, that would be his Swan song.
Was the transformer in question the blueprint you were looking at?
Thank you for sharing that superb explanation, Paul.

That would be the Peerless S-268-Q. Indeed, it is a complex transformer to make. The test sheet for this blueprint shows that it was able to pass a clean 30KHZ squarewave. I'll have to pull the blueprint to cite some of the other cool features of this design.I'd still like to make it my swan song! Other than the Peerless TL-404 autoformer and some of the very early Freed small signal transformers... the 268 would be my most challenging undertaking. Peerless only ran (by memory) the 268 in two very short runs due to the difficulty of their manufacture.

Likely the 268...the 265 is relatively simple. The 271( which is more closely related to the 268) is substantially more complex than the 265...:)
