this is umpteenth time that Pa pulled my leg up to the sky

- corrected schm after 290 replies
nah, Mr. Pass put my little gray cells to work; like the younger ones for many others. Was, and will be an interesting F6.
whatever
we can now proceed to test Um variation of said circuit

David Copperfield is little kid , comparing to Papa

David Copperfield is little kid , comparing to Papa
again - as drawn by Papa in post #1 , those two secondaries are in phase
and , at least by my limited knowledge of English , he confirmed that
like always - Devil is in details
look at this - just little re-drawn , for clarity sake
blahblahblah
so now , after Papa merciful waiting to bring us proper schm ( Oh , I didn't saw that mistake ) , let's make short - this time proper - analysis :
besides biasing , simple Greedy Boy can freely expect few more tricks ......
maybe yes ........ maybe not

I'm just staggered -- i bought a couple Jensen jt11-ssp-6m transformers off ebay a few years back for $40 -- they're now $132 apiece!
Really, it was an honest mistake. The only mystery is how the circuit
worked so well that way...

I believe that ......... ( I'm really trying !!!!

well - that I can't believe

except if you made Um variation

Are you mistake in this drawing intentional? 😎
I was right....misdirection! I am going back to ugly cousin, bastard R085. Gonna try CCS, ALeph CCS, and SRPP. Now that i think about it, the Srpp could be plugged int this circuit...no no no. Get back on track.

naah
not same thing again
this time I'm double double sure

Preferably by simulation. Fet cost is steep.whatever

I have a theory on that.

moi again ....... I flipped unflippable so many times , so my flipping brain was flipped again 😛
to repeat proper one - just for the record

Will this blow up?
most probably not
but biasing must be adjustable , to achieve proper 0 on output

Forgot about bias pot for upper fet.

It follows that:
- The output FETs are/must be highly matched [within the grasp of the DIYer].
- Circuit operation appears to be highly symmetric. When the upper FET is relatively on, the lower one is relatively off. When the upper FET is relatively off, the lower one is relatively on. The 2 ON states are made equal, and the 2 OFF states are made equal too. This is symmetry. Correct asymmetry with loop feedback.
