Bonjour Serge,

Serpentine, quel sont les puissances (environ) des toriques testés?
If I understand this right, you mean the VA-rating?
RFT: 33VA
Bürklin: 30VA
Holzinger: 150VA
Unknown: 150VA

The Hammon 125 gapped audio SE is rated 15 Watts, 80mA Idc (a little bit optimistic). The Engel A4 gapped audio SE is rated 4 Watts, 50mA Idc.
I am very

because the Bürklin units I bought for the ECL82SRPP after having done the load matching using the RFT unit perform so much worse than the RFT unit ... but such is life
By now, it is neither clear to me which tube parameters (types) are suitable for power-SRPP, nor which toroid (except for impedance, of course). This obviously is not an issue of correct load matching alone, and toroid construction definitely has a very large influence.
Maybe you and me only had much luck having used toroids of suitable construction merely by chance ....
I suggested to Yves to send him the RFT (good) and Bürklin (bad) units for further analysis, but he didn´t responde so far. Since I am off to ETF06 for a few days soon, I will just send them to him, if he wants or not
Maybe Yves will find out what is going on.
