Default Studio Monitor Amp from AWA BAM-2

Hello again from Tasmania. I came across a few 70's model AWA studio monitor amps as used in many radio stations around Australia, including the ABC.

The model # is BAM-2 and they have been designed beautifully from the best of components (70's components that is) there is a bit of Germanium in there and isolation transformers as well as a few huge 2000mF (uF) electrolytic caps. The amps are class B & rated at 10 Watts/16r and have a smicko little square ~60VA transformer that has been encased in some kind of plastic shielding. I think the amps have a 600r input, so they would be Ideal for my Sure Bullett mike which is about that impedance from memory.

the amps came in a heavy steel rack case measuring about 6" wide x 5" high x 12" deep.

I would imagine that a few of these units are still in commission around the traps, so if anyone can get the schematics to me, then I can get them up and running. In fact I'm pretty sure they are servicable now, but they have a modular plug on the back that mixes up the 240 volt wires with the low voltage stuff including the input, so I would just like to identify the conductors on the 16 pin/conductor modular plug and remove the 240VAC to a safer place.

Yours sincerely, Phil
