Hi

I recently acquired a Farfisa Matador electric organ (made circa 1970 I think), which needs a bit of maintenance. Does anyone know of any vintage organ experts in the Auckland region? Or non-vintage organ experts who might be able to fix it? Put simply, a couple of the notes start to make disgusting sounds after the organ's warmed up, and a couple of the keys stick. I've taken the cover off and had a poke around, but it's all pretty foreign to me.

Any takers?
