I've just been turning the idler down a bit. This has got rid of the dink where it had been pressed against the motor shaft for years but as it's so hard it rumbles like hell when it's going 'round.
Putting a rubber band around it gets rid of that but it very quickly flies off so I'll see about gluing one in place.
The radio side gets ever odder. This morning I thought I'd see what the alignment was like. I didn't know what the IF should be so hooked it up to the Nombrex and swept around the 450-470 kc/s area. Not a peep was heard. More or less by accident I found it at 100 kc/s. The first IFT primary was about a quarter turn out and and fixing that has improved things a surprising amount. Frankly this beggers belief so I'll check it again with the Advance when I've cleared enough space to rig it up.
