[QUOTE="Greg Cameron, post: 64997, member: 42"] Re: A&H GL2200 repair; right channel drops volume. Check and see if the fader connections use crimp pins on the wire connections. For some reason on a particular batch, A&H used crimp on pins on the wires to the faders, and then would solder the pin tip to the fader lugs. The crimps oxidize over time and loose connection. Depending on which ones, you'll either lose audio on those channels or it could go full gain if the ground lets go. In any case, you can either cut off the pins and solder the wires direct to the lugs or just flow a good amount of solder into the crimp. I had at least 8 channels start crapping out due to this.
