To adjust the coil, with the set on and tuned to a channel, turn the coil slightly in one direction, less than one turn, then interrupt the signal by switching to 04, the back to 03. Each time the coil is turned the set needs to fine tune itself that's why the signal must be interrupted. Also check and clean the sharpness control on the back apron of the chassis. The sound may be cleared up by aligning coil L201, it's just in front of the audio IC where the speaker wires connect. This coil uses a different alignment tool than the AFT coil one. There should be a paper chart in the cabinet that show these parts locations.

adjusting one of the AFT balance trim pots helped a little bit.
Adjusting L304 really affected things.
I wish I could tell you more, but the ceramic bits I ordered are too #$%^&* short to properly reach the slug... so i'm waiting on a set of proper coil alignment screwdrivers.
Also sprayed deoxit into the sharpness control.
