The rear panel, just below mains lead is a TOSLINK connector, used to send signal to a remote mains switching unit to power up source components.

Internal view, the circuit design is one of my own. Anyone recognize the metalwork of the power amp modules ?

Each amp module has D.C. protection P.C.B. mounted on right side with local filtering on left P.C.B.

The PreAmp. All input switching done at sockets with MOSFET,s in series shunt arrangement. Full remote control included Volume and input selection. All PC.B.,s hand drawn (took hours) just getting to grips with a C.A.D. Package so feel another project coming on

A poor pic part of preamp, the board at the bottom is a "hardware solution" to what should be done in software. The remote decoder is under the white plastic cover and I had to buy this in. Fully learning it will accept any "common" r/c commands, my pcb decodes the outputs and translates levels to operate fet switches.
