I just happen to have a dinosaur Sunn 4 channel dimmer pac and $20 + shipping ($5??) makes it worth my time to box it for you. If you lived here you could have it. Here's a Craigslisting for one like mine in another city - http://syracuse.craigslist.org/msg/2525673120.html call 727-421-9045 or email Slim at SarasotaSlim.com because I don't check here as often any more.
Hi Ben. I have 2 made in USA Lightronics Stage Control dimmer packs, model AS40 (you can look on the net for specs). They're 4x600W and in very good condition. Let me know if you want to see pics. $100 shipped for the pair.
Contact me at [email protected] if interested. Thanks, Lev.
