Of all these things the only thing that has not been really explored is the use of the Webster push pull transformers in a single ended application. Everyone that I know that builds or is really into SETS prefers AC on the filaments. The Fi circuit or various variants is all old news. Those circuits and SRPP, Cascode Mu Follwers all can be very good. I have 7062 / 45 and a ECC40 / VT52. My next unit will be a little different with a KC1 /112A/45. At some point, I hope to have John build me a unit or I'll get a pair of Webster/Hammond/Conn output transformers and give them a try. What you could possible e hearing with the Webster's is some very pleasant distortion. I don't know if, in the case of the 45, the primary impedance of 5K is available on the Websters. That would be a question for John. If it is lower than 5K, you are certainly getting more distortion. Mind you, I am not saying it does not sound good, I am sure it could be additively positive in some cases. You listen to music, not measurements :)
