The original would have had 2 volumes and 1 filter for the controls. Most of the time we supply with volume/blend these days. There won't be any new goods like this in the UK to my knowledge, but you might find some spares from other club members (I'm looking at you, jazzyvee!). Otherwise, you will need to import yourself, but that's relatively easy. You can order from a dealer like Will, and we would simply ship the order directly to you.
