You're right. You've got a leaky cap(s) somewhere on
the AGC line. If you so much as show a picture of a ten
meg resistor to that line it will bury it's head in the ground.
You also may be missing the jumpers on the back panel or,
least likely, your AGC amp is weak. Finally, there is always
the chance that the radio simply doesn't like you, and would
work perfectly for somebody else, like Barry the Beggar.
