I'm at a turning point in the fabrication of my new sound system, and am looking for a little help/guidance. My plan is to semi-permanently install my Peavey XR684F mixer head into a rolling cabinet. Adequate ventilation will be provided, and the head will be secured in place within the cabinet structure. However, I would like to remove the handle from the one end, the better to center and secure the mixer in place. The handle is a strap affair, rubber casing over a metal strap, and it is secured through the case at either end by a Phillips head machine screw driven through the handle and into the case body. I could, of course, just pull the two screws. However, I have no way of telling how they are secured within the cabinet of the mixer, and am afraid that I might be dropping some nuts down into the cabinet where they might short something out. I would open the cabinet if only I knew which of the myriad of machine screws on the thing would allow me to do that. It shouldn't be complicated, but there's no way of telling without a service manual that addresses such issues. The one available is limited to a bill of materials plus a series of circuit diagrams - nothing about the cabinet at all. I'd take it to the local repair facility for Peavey products (Evans Music, out on Westheimer Road), but they have a $60.00 minimum charge, and that seems a bit steep if all that needs to be done is to pull a couple of machine screws out of a pair of internal T nuts. Does anybody hereon know anything about the Peavey XR68XX series of mixers? Any help here will be greatly appreciated.
