As other people have warned, one or more of these contacts
could be at live potential, I didn't check, because I was using an
audio isolating transformer (I think it was from Tandys).
I had to move the loudspeaker connections to the other side of the
transformer (so the cut-out would work correctly). Trouble was the
transformer lost some power, so you had the turn the volume up louder
than before, which caused it to distort if you wanted it loud (but
normal viewing was ok).

I'd say the ideal cheap transformer would be a telephone line isolating
type if quality isn't that important. A good quality audio isolating
transformer won't be cheap.
