May I suggest that you update your knowledge with the novel single ended output transformers? I recommend the corresponding article of Pierre Touzelet in the May 2013 issue of AudioXpress.
Pierre has demonstrated with his authoritative mathematical style that the SC-OPT developed for single ended amplifiers works exactly, under certain conditions, as the conventional, gapped OPT.
This kind of transformer is suitable for any quiescent dc value, opening the way to powerful S.E. valve amplifiers .... etc.
You seem to be very interested in the construction of audio transformers and this is an opportunity to reconsider the idea that "nothing can be invented in this field". Please do not use the "ipse dixit" attitude.
I'm open for further information, if requested.
Cheers,

Hello Patrick, I would like to add that you can find more information on the self-compensated OPTs in the European Triode Festival Site (Year 2008- Lectures) and, if you have access to the AES papers library, see Paper 6346 AES 118th Convention - 2005 - Barcelona, paper 6831 - AES 120th Convention - 2006 - Paris , Paper 7151 - AES 122nd Convention 2007 - Vienna ).
Should you need more information, please do not hesitate to contact me at my site (polisois-audio.com or by e-mail ) and I'll be glad to respond.
Best regards,
Ari (Audiochef)
