AM6/11, UN14/9, ADR F600-LB

Jonnie Wacker is looking for a schematic for an AM6/11 and analogue delay UN14/9. He also has an old BBC rack that contains an ADR F600-LB limiter and some PYE mic amplifiers (the type with half moon faders) and would like to get hold of the pinout/schematics for these units. "Thanks for the help much appreciated."
