I have just purchased my first machine. I am very ignorant about these lovely machines but want to learn. So sorry as I'm sure it's a really dumb question.
I took a look at the batteries. There are three in the holder, and they look nice and dry, no corrosion etc. But I was surprised to see they are all oriented in the same direction - i.e. positive at the top for all 3. With other devices like my radio, etc the batteries are oriented so that they are in series, so positive against negative etc. Hope I have explained that clearly.
So is it correct that all 3 batteries are pointing in the same direction, so presumably in parallel rather than series?
Also one other initial but dumb question. Its a 1979 Williams machine (solid state). Will everything be running at low voltage, i.e. does it all go through the transformer or is there likely to be parts at full mains voltage? I'm just wondering how careful I need to be when messing about with it.
