You assume Nelson is going to give out the schematic.

well - I had impression previously - when he first time mentioned F6 - that he'll share that .

dunno - now , when you wrote that , I'm not sure - didn't asked .......

whatever - enough info is here , along with already shown bits and pieces how to bias SJEP in simple way

I'm excluded from game , too much of insider info , tnx to my resident spy in PL cousine

Figured it might be like J2 and M2. Doing it is one thing, like Nelson is another. We both know he has some quirk thrown in there.

luckily , his quirks are heading to simplest possible solutions , lately

after deciding how to bias outputs , all one needs is to play with few variations for Rs , and few possible feedback amounts

I wouldn't choose M2-J2 biasing arrangement here ; it's possible with highish Rs , which I'll try to avoid

(just my opinion , not result of spy cam capture , situated in FW facility )

Got some decent transformers in a trade. Should get them this week. Will have to hit up Tea for some fets. bias could be really simple, think, but don't know about effectiveness.
