Thank you Trigon, you have cleared up my confusion. I didn't realise the "links" on the circuit diagram were switch contacts. Paul, you are correct. The "radio/diode" socket does have an input and an output. There are 3 inputs in total. A low level microphone input, a high level input potted down by a 1M and 22K resistor and another input potted down by two 22K resistors. There is also an output from the anode of the ECL86 audio amp triode that goes via a 0.1uF cap and is attenuated by a 220k and a 15k resistor. Thanks again to everyone who has replied.

Regards
Martin
