Hello, everyone,

Does anyone here have the service manual or schematics for the Allen and Heath GL2800 or GL3800? I am mostly looking for the master section (Left PCB as written on the board) and group sections. I have the service manuals for the 2400, 2800M (monitor version), 4800, and 3300, but not the 2800 or 3800, both which use the same master section PCB. I'm wanting to change the fader make up gain for a client to hopefully reduce the output noise floor like I have done for other consoles.

Thanks!

Paul
