Hi, I started measuring transistor voltages, I think I have a serious problem, The very first measurement with Q6(2n3053)
B         C         E      Q5 :    B(3,2v), C(25.6v) E(2.7v)    Q4 : B(1.02v) C(4.15v) E(0.45) 
2.73V ,27.3V   2.23V   ,  have I wired my O/P transformer( HBaudio UA5002) wrong. I followed Skylars wiring diagram since I have mnats pcb's and CONNECTED those yellow/orange wires together. Although a signal is passing through and compression happening, front panel controls are affecting the signal and VU meter reacts also?????
like I was adviced to do on this forum, I have checked everything else in the signal line amp: resistor values all caps, and exact 30V on the O/P transformer primary's black wire!
This is somethin really weird, so I would greatly appreciate of any kind of help!    ....I can't figure this out by myself!
Regards jyrki3101
