Yes I am confused as to the results as well. I'm not totally sure if being #1 means that harmonics are higher or lower although I think it means lower?

Hey spread,

So you where unable to read post #9?

If anyone wonders about "MJK-style parafeeds with Schaded 6L6" this is a parafeed AC-coupled version of this:

So you have corrected the errors or haven't? Do you have a result or not? If so, what is it?

EDIT: I really do want to know what the result is.

Read again. Posts 10&13&19. Might come back when the SEPTOR(its in the linked thread) is rebuilt for MOSFET mu-follower, not AT. If going for mu-follower, forget tubes, they have to low gain/gm to reduce un even harmonics.

As MJKs 6L6 hybrid have a little to much odd H it will probably be helped by a follower. Will come back with a schematic of how I think it should be done. and what the indications are.

Lars, it is very similar to my Nirvana. I can't tell now more than it is the right way to go.

Would it be possible to have an simple version of this for dummies please?
Out of the initial 3 circuits posted, which was the best and which was the worst, and what type of circuit should we be preferring?

TIA./
