Now: I removed Z1 and found the voltage measured at the collectors
of Qs 1 and 2 to be -0.4V (J3+ is ok now). I don't know where it
could come from.
Hi Gerhard:
Dunno if this is related, but I got a small voltage J3 by shining a
bright light on the final transistors. There is some sort of
photoelectric effect.
Your numbers are close to what I measured then:
