Until I get some JFETs the sim is all I have at the moment..

And what's wrong with 3rd harmonic? I estimate that at any given
time, about 1/2 the buying public prefers 3rd over 2nd.
Where lies the critical part corncernng the circuits sweet-spot?
Is it the current through the JFETS (8mA) or the current though the MOS-FETs (1.3A)?

Hi!

Is it normal to check FirstWatt site 100-times a day to check whether there is a F5 article there or am I just impatient? ... and I cannot buy magazine anywhere :S
Can anybody "save" me?

Thanks,
Matej

My idea was to "match" an upper set (JFET-POWER MOS) and a lower set ditto, instead of the typical lowpower/high power match?

I'm not sure that will work for you. Much easier to hold your
horses until I complete the write-up on tweaking it.
