what I was suggesting was that perhaps the forum might want to look at the Williamson transformer design that is in the public domain. To my recollection it is a 10K pp primary with all of the appropiate secondary taps.

This design could be built with taps at differing points on the primary to make it useful for the Merlin amp.

And it could, as perhaps you suggest, also be useful in a "true" Williamson style amp. And a Triode PP amp. And the uses are manifold.

what I was trying to say is that... since it is a public domain design.... all of the details could be posted without stepping on anyone's toes....

with such information freely available.... folks could get together for a group buy or alternately go it alone and get a pair made on their own.

the beauty of the proposal (in addition to it being, actually, a pretty decent output trans design) is that now no one has to pirate the property of any other forum member to get a device useful for the implementation of their forum derived amplifier plans.

And of course it might then also encourage more circuit design activity as well as, in the public domain, refining the public domain transformer design to yield even better performance.
