Fionn Posted June 17, 2013 Share Posted June 17, 2013 I'm looking to replace a tone/ volume pot on my old Aria SB-900. It's a 500k / 500k stacked (concentric) pot with a split shaft. I've looked on every tech supply website that I can think of. I can find a 500k/500k pot, but [b][i]not[/i][/b] with the split knurled shaft that I need. I've also emailed Aria twice (with no reply). Does anyone know where I can find one? Quote Link to comment Share on other sites More sharing options...
MiltyG565 Posted June 17, 2013 Share Posted June 17, 2013 Pardon me if I sound like an idiot, but is the split shaft that important? If it is, what's you stop you sawing a split into it yourself? Quote Link to comment Share on other sites More sharing options...

The split shaft pots have a larger diameter of shaft, and are knurled to provide a key within the knob. The knob is held on by a small measure of tension (not a grub screw), hence the necessity for the shaft to be split. Quote Link to comment Share on other sites More sharing options...

So can't you get a solid knurled one and just cut a little bit out of the middle with a very fine saw? Or get a slightly smaller solid one, and put some tape around it to provide some extra girth, hopefully giving it the tension it needs? I would doubt it would go very far if you did it that way.

ikay Posted June 20, 2013 Share Posted June 20, 2013 Can you post a pic of the pot you're looking for? From your original description, the closest I've found so far is this one but it's the wrong value (50k): [url="http://www.wilderdavoli.it/app/prodotto.jsp?tipo=2&IdC=321&IdS=0&prod=p&id_prodotto=1043&id_categoria=71&prod=p&css="]http://www.wilderdavoli.it/app/prodotto.jsp?tipo=2&IdC=321&IdS=0&prod=p&id_prodotto=1043&id_categoria=71&prod=p&css=[/url] Quote Link to comment Share on other sites More sharing options...
