Dennis,

I took out the IF deck and measured resistance from pin 6 to ground, and I 
see about 7 meg with no charging behavior. it says I should see infinite 
resistance.
_____
If you were doing this in 1970 with a TS 505 or a TS 352 on the K ohm range, 
7 meg would be infinite resistance. You are likely OK on this test.

TM 11-5820-358-35 8 Dec 1961 Para 72 b. Alignment of Z503 Page 113.
says AGC should be in the range of -1 to -2 volts

My mail only goes back 5 days, so I do not have your original problem
with your AGC.

Watch the other responses and keep asking questions until you
feel you and your receiver are happy.
