RE-ASSEMBLY
PCB710 - Re-assembly is largely obvious after dis-assembly has been carried out. However, care
must be exercised when re-fitting the main PCB to ensure the rear panel sockets align
with the rear panel apertures before sliding the PCB towards the rear and downwards
onto the mounting studs.
Do not over tighten the Neutrik output socket retaining screws. (6 off)
PCB701 - Reverse of above dis-assembly procedure. Ensure connections on underside of board are
made (J105, J205)
