Thanks for the replies. I hadn't been notified of them, I'm afraid! I'll look into the electrics momentarily and trace that path.

The 4A is still having its grotty cabinet material removed, but the chassis are cleaned and I have replaced the old Bulgin with a new IEC Bulgin that screws to the same holes.

I'm still wary of attacking the tape head assembly to clean it. There looks to be some general gunk and possibly corrosion, at least on the plate they attach to.

Can I do any harm with a cloth and isopropanol for an initial go? Anything I shouldn't touch?
