I have begun restoring an ARP Pro Soloist that is total junk. I found a company called New England Analog that sells parts for ARPs and does restoration work. The owner is Rob Currier. I just want to give all of you a heads up if anyone needs ARP work. This guy is a first class guy. I bought some parts from him but more importantly, he walked me through a whole bunch of procedures and solved a number of mysteries for me, probably saving me a couple of dozen hours. He was not only willing to help me before I bought anything from me, he told me what I DIDN'T need and saved me a lot of money. You don't often find folks like this so I want to recommend the guy. I've seen his work and it's first rate.
