Thanks for that. It looks like the PCB takes the strain when you pull off the knob, so thanks for the tip about grabbing the pot with pliers - I guess there's a danger of damaging the PCB by pulling too hard otherwise.
It looks like finding 3mm shaft pots is tricky, but I found a couple of different ones at Farnell - I've ordered both to see which gives the best fit- it doesn't look like either have a flat on the shaft so a bit of filing might be necessary.
If anyone knows where to get exact replacement 100k 3mm flat shaft 16mm pots then do let me know!
Cheers
