Because I was being quite careful and manually logging everything so I could put everything back together without probs, it took me half an hour or so.
Now I've done it and know what to expect, I'd be able to do it in about 10mins or so. Basically it was just a case of having the courage to unscrew all the several sets of layers for the first time, and decoupling all the ribbon-cables (simple enough, but there's several of them that look identical), etc..
Getting back to the pots, here's a quick pic:
Pot 1a
...The part that is actually wobbly isn't the spindle itself, but the metal part surrounding the spindle that fixes the spindle to the base of the pot. I've placed a dotted line along the edge that's causing the prob, so it's easier to see:-
Pot 1b
From another angle:-
Pot 2a
...and with a dotted line again:
Pot 2b
Because the actual pots themselves are working flawlessly within themselves, I think I might first try injecting a little superglue in between the two little metal tabs either side of the base of the spindle using a fine needle syringe to see how that holds. And if that fails, I've lost nothing, and so then I'll then replace the pot itself as I was going to anyway.
Will need to get the components in anyhow, and it's about time I got myself a nice soldering iron and solder-sucker, etc..
Beware of crap soldering irons. And, moreso, crap solder!
