Thanks chaps and ta for the links Jeffrey and Lawrence. RY2 does indeed look like a R53 thermistor. funny that the thermistor is worth more than the whole thing. Your right Terry, of coarse + ground makes sense if using germanium devices as they're PNP, didn't think of that. Why do you think they used germanium devices, surely silicon was cheaply available in 76?
So you think it needs an AC power source rather than DC Simon?
Video here - https://youtu.be/RG-SJm-FxqQ, you'll be able to see RY1 & 2 clearer and understand a bit more (hopefully) what i've been waffling about. : )
