RE: "...the source Z is truly awful..."

Lew,

If you read the notes from EEs JLH and Swenson, (which I believe I sent you), source Z is systematically discussed, mostly by JLH.

He points out, it is HARD to obtain a source Z of under 400 Ohms with a conventional / traditional L-Critical choke input.

JLH then shows us how the "modern" (NON L-Critical) supply he uses can obtain a source Z of under 100 Ohms. 85 Ohms as I recall.

Then he goes on to pose a question to us all " Which supply will power the 300B Finals better, a source Z of under 100 Ohms, OR 400 Ohms ??"

Its all there in the compilations I send people.

I rest my case, on this point.

Cheers,

Jeff Medwin
