Picked up a few more radios

its been a while bit IIRC i had a allied 333 that did the same thing, AFC made it worse, I think its how the discriminator coil is adj. the AFC looks to adj the LO until there is null at the output of the discrimator indicating its tuned to the IF frequency. If the discriminator is not set right this null take place somewhere above or below the IF frequency.

I think I was able to make minor tweaks in the secondary of the discriminator until switching from AFC to non AFC did not effect the signal strengh or sound when the non afc is tuned perfectly. Of course any time messing with IF you need to be sure which side you are adj the afc line secondary should swing from pos to neg quickly when adjusting the secondary of the discriminator.

again its been a while....
