Can you still get parts for CH Pro Pedals?

My pedals sat idle for a few years and I think the pots have went bad. They started out with a lot of static and unwanted movement and finally stuck in a hard right turn.

10 years ago when I bought them CH stocked parts for their items but when I called them more recently they said they had quit stocking parts. Does anyone know of a source for parts for my pedals? I found some electronic supply shops on the internet but they had literally hundreds of pots and I have no idea which one I need.

Thanks in advance;
