The coil and capacitor thing is just an electrical noise suppressor. It can be removed and bypassed with no ill effects at all, except that people listening to AM radio in the same room will be annoyed.

I thought that's what they were for. The capacitors had three wires coming out of them instead of the usual two, which I had not seen before.
Thanks.

Those are 'Y' capacitors - two in one package, one for each line, with the common connection going to earth. This being a post-war German machine, the earth wire is red. This is what the modern kind looks like - note the 'Y' capacitor on the right - the Wulff version has an extra stage of two small chokes and a 'Y' capacitor following on the input side.

Mine seems to work OK, but I can't get the lights to work. There is a pair of red wires going nowhere, see pic. Does anybody know what fits in the hole just above said wires? !PUZZLED! What's the fuse rating that sits on the transformer?
Thanks.

The fuse is 3a. The Black thing is a latching push switch.

Brilliant, :D , but what's the function of the latching push switch?

Ha! - I knew you were going to ask that - I'll have a look this evening...

Comparing the two photos it looks as if the latching switch controls the 3A power from the transformer to the machine.
However the wires (red ones) that would have gone to the switch are sitting coiled together but not in contact so the circuit is still open.

There also appears to be other bits of electric string haphazardly slouching around, so before you start prodding anything make sure you turn the volume on your electric meter up and stand in a bucket of water. I might have got that bit wrong. !PUZZLED!

The missing switch is for the play-field lighting. When the switch is open circuit (like it is now) the lights will only come on when the game is being played; with the switch closed circuit the lights will be on all the time the machine is plugged in: "display mode". :didact:
