F6 Amplifier
 
1 Attachment(s)
ZM has been nagging me for information on the F6. I have a very nice
sounding prototype, but the design and the article that accompanies it
have some details remaining.

However, I can afford to put out this teaser:

:cool:

Interesting. Why the transformer?

looks promising
 
I am doing a similar thing with tube front and vfets output.
Not sure about the feedback setup.Will be an interesting read.

The Devil is in the details.

Having only n type output devices - reminds me of tubes.
Could a jFET be used as a phase splitter instead of the transformer ?

I take it the voltage gain stage would have active regulation
and the current section would have passive "regulation."
