fine work Kamel and Botte......!
Zen Mod must be in the wrong thread.....doing gymnastics or he is coming from a party....or he tries to do Bavarian dancing.... please tell us ZM...
Bavarian Dancing , off course
just imagine me in Lederhosen
ok - simple explanation without elastic thingies :
ya see Q3, Q4 and R13
presume that PSU voltage is +/-22V5
let say that we are going to replace both Q3 and Q4 (along withtheir source resistors) with (variable ) resistors with value of U/I=22V5/0,045=500R
DC is flowing from Q3 to and through Q4 ;
now imagine that we are giving some sine on input , which result in opening ( down-going half cycle) Q3 and resulting in halving that virtual resistance of 500R , so we have 250R
DC can't go entirely to Q4 and must go through R13
but - in same time , same down-going half cycle is governing Q4 too , resulting in increasing it's virtual resistance to 750R
result is that current flowing from Q3 have even lesser possibility to flow through Q4 and that difference must go again through R13
now - turn schm for 180degs and repeat mental gymnastic
simple , isn't it - same as two hands and rubber string
....
can I be your representative for Germany ZM ?......
only if I can park my spare Lederhosen in your flat/house/apartment

Pa is a man with multiple virtues
one of them is that he doesn't care too much for numbers , sometimes .
frankly - I didn't build that stage , I didn't calc it's gain ..... and I don't believe too much in numbers , too
(but not from same reasons as Pa ; he knows da numbers , I'm dumb for that )
Generg - what's gain of your BA3 FE , built by the book ?

Ha, then you don't really live in Mannheim.... BUSTED!Naah park them at my Place, which is only 30km away from Okoberfest
Although it may feel like 30km, if you can hear all the hooting and hollering coming from the Paulaner Tent...
Sorry, OT, but I can't really contribute anything to the thread itself.
Of course, inherent to classA
a current increase in the upper Q correspond to an equivalent decrease in the lower Q
I was on the moon.
elastic wasn't talking to me.
