Default Re: Electron Kinetics Eagle 2C amplifier problem

Sorry for the lengthy thread! Here are the voltages from the transistors I measured from each side:

(CHANNEL A) Top Transistors
#1 Sanken (2SC2774) B=.631 DCV/ C=48.0 DCV/ E=.018 DCV
#2 Sanken (C2168) B=1.22 DCV/ C=47.7 DCV/ E=.627 DCV
#3 Sanken (2SC2774) B=.626 DCV/ C=48.0 DCV/ E=.017 DCV
#4 Sanken (A958) B=46.4 DCV/ C=1.22 DCV/ E=47.3 DCV

(CHANNEL A) Bottom Transistors
#1(2SA1170) B= .603 DCV/ C= -46.55 DCV/ E= -.012 DCV
#2(A958) B= -1.22 DCV/ C= -46.33 DCV/ E= -.600 DCV
#3(2SA1170) B= -.593 DCV/ C= -47.3 DCV/ E= -.002 DCV
#4(2SC2168) B= -44.7 DCV/ C= -1.20 DCV/ E= -44.8 DCV


(CHANNEL B) Top Transistors
#1 Sanken (A958) B= 47.8 DCV/ C= -40.0 DCV/ E=46.1 DCV
#2 Sanken (2SC2774) B= -21.0 DCV/ C= 46.8 DCV/ E= -19.6 DCV
#3 Sanken (C2168) B= -18.8 DCV/ C=46.8 DCV/ E= -18.9 DCV
#4 Sanken (2SC2774)B= -18.75 DCV/ C=46.9 DCV/ E= -19.4 DCV

(CHANNEL B) Bottom Transistors
#5 (2SC2168) B= -44.8 DCV/ C= -2.27 DCV/ E= -44.8 DCV
#6 (2SA1170) B= -1.15 DCV/ C= -45.9 DCV/ E= -.63 DCV
#7 (A958) B= -1.9 DCV/ C= -46.7 DCV/ E= -1.22 DCV
#8 (2SA1170) B= -1.42 DCV/ C= -46.1 DCV/ E= -.75 DCV
