It seems i'm just too eager to think i've found the problem , i swapped qe 29 and 30 then turned the amp over and felt the new transistor again , so it seems QE is NOT the problem , i will check the other voltages and get back to you
all i can suggest right now is swap qe26 for qe25 like you was going to do earlier ..
qe 18 collector connects to qe20 base and is a bit high ..it should be -400mv ..this may be a problem .
