Jim:
Checked our 85 AFM, measured 561ohms between 3&4. FWIW 2.3kohms in
parallel to 740 will produce the requisite 560 ohms. I know there is a
schematic for the AFM but can not locate. I will keep looking. On page
24.28 it is stated that 500 to 1000 ohms is OK. This confuses me because
I also have seen that 560 ohm spec somewhere.
Good Luck
