You really need to use some common sense , stop relying on those two clowns' dogma and go your own way
Transformer winders tend to balance the copper losses between primary and secondary when producing a design . You can reduce losses by using thicker gauge windings but this means less primary inductance or a bigger core . All output transformers have losses , in fact , I believe this is the most lossy part in an SE amplifier . If you have a DCR of 200 ohms in the primary and 0.8 ohms in the secondary then the DCR of the leadouts is irrelevant no matter how thick the wire . So much for 'transfer function' when you consider the DCR involved !!!

I've actually learned some good things from JM that I use all the time.
The more I get into higher quality/high efficiency transducers like Altec , the reality of some of his ideas starts to make more sense to me.
I got my rebuilt 414-8B's back from GPA , got the t/s parameters measured and hope to get them in the test boxes this weekend.
My system should take a step forward in efficiency since the 414's measured over 100dB/1W/1M.
' the reality of some of his ideas starts to make more sense to me.'
You are obviously easily influenced by those who shout the loudest . The vast majority of these 'ideas' are based upon junk science , dogma and narcissism . You would be better off finding your own way , you seem stuck on this whole DrLowMu/Dennis nonsense . It's not healthy...

I fell prey to the influence of megalomaniacs.
Woe is me.
Liked it .
