Hallo Mr. Risch,
first of all, many thanks for your kind reply.I'll avoid to repost the schema (as I see my fonts already in courier, ASCII), anyway it is largely as the one with 4 trafos as on http://www.audiocircle.com/circles/viewtopic.php?p=204498#204498.

> under control to some extent. I prefer parallel resistive damping at

> more than about 10-15W anyway, so size the resistance accordingly.Many thanks,
Stefano
