Hi Nick,?
I got a replacement from yaesu, not very expensive at all.?
When changing the select pot make sure that you remove the battery before doing anything else and replace it last. It's not a hard job but take your time, the rubber buttons can be a fiddle, lots of flux and a big iron to unsolder it, a good clean up of the pads then solder the new one in.?
