Thx guys!
Starting on the top side of the chassis, the grid cap wires for the IF transformers needed to be replaced or sleeved as the insulation had worn away where they come through the IF shielding cans. Some cleaning inside the can wouldn't hurt either. I removed the 4 screws and two nuts on the can tops and pinched the 3 sets of spring clips (one at a time) that slot through the chassis to underside to then worked the can off the 3 transformer coils. It was relatively easy except that one of the ceramic pieces above the coils was rather tight inside the can and required a bit of prodding with a small wooden dowel to force it out. I opted to put a small section of heat shrink sleeve on the wires and after cleaning things up tried sliding the can back on....
That ceramic piece was just not going to slide back up into the can. I was able to put some threaded rod (6-32) into the screw holes of the ceramic so I would be able to work the ceramic piece back up into the can. That and some wire tacked onto the grid cap wire so I could thread it through the can allowed me to get it back together.
