OK got the Sams.
IC 400 & Q202 are the AGC semis. Also some eletrolytics
C420, 215, 216, & 211. Also C130 1mf probably mounted
on tuner at AGC terminal.
There is NO AGC adjust at all.
Normal range at IF board pins are
TA22 4.43- 11.31VDC
TA21 4.62- 9.56VDC
Tough to call this one could be AGC or IF dont think video.
Hard to tell not being there.........
