hello all, I need some help here, I have just purchased a SUNN Magna 2480 mixer through ebay, the mixer pilot light comes on but I cannot get sound out of any of the modules. I was sent to a repair shop but due to lack of information was unable to fix the problem, does any body have any information about this mixer? any user/service manuals or any idea. I was told that it could be the transistors. This is a very cool piece of equipment that I would love to get working PLEASE HELP
