Hi all, I was restoring a Panasonic RQ-SX60V last night and the final step was to tweak the speed adjustment as it was running a little slow. On adjustment the plastic material that the speed pot is made out of crumbled to dust. Perished with age. I've scoured through my scrap RQ-SX models and can't find an exact match. The pot I did use doesn't work, its either full speed or off. So it seems each RQ-SX model may have some slight changes in parts. Question is, does anyone know where I can find a replacement speed adjustment put for the RQ-SX60V? Or a scrap unit I can source for parts as the one I was working on was near pristine before it packed in.
