Well, this is my first post. I found a Sunn SX8350 on a trash pile. The guy throwing it away said it had been left in the attic by the past owners of the house. He didn't know anything about it and said for me to take it. I did and checked it out. The unit is electronically in excellent condition. It works great and the only thing wrong(you know something had to be wrong,right?) with it is that a few colored caps on the knobs are missing and the 63Hz slide controller is missing the stalk and knob, but you can still set it with a tooth-pick. I downloaded the entire owner's manual off the site and I thank you for having that available for me. I play keyboard and am thinking about setting the unit up with an electronic sub crossover to operate a sub woofer. The keyboard its a Yamaha TYROS and has a selective out for the bass. I am running powered speakers for the L & R channels. That is one idea. I am open to other ideas. Thank you for the web site and any help you might provide. Now I know more about what I have and what a lucky find I made. How about parts? I would like to get some knob inserts (missing two light blue and one gray) if possible and fix the slider.
