Somewhere in another thread I specifically mentioned the unreliability of electromechanical parts. I was trying to find that posting hoping to quote myself, but I couldn't locate it.
Andrews' response was something like "But this is mechanical TV, the more moving parts the better."
Well, it's come home to roost.
Also somewhere else I said to Andrew, "If you have a known faulty component, or even just suspect that it's defective, throw it away. It will come back later to bite you on the bum when you've forgotten it's faulty". How's your bum feeling?

Another thing worth mentioning is about soldering irons. If you drop it or it falls off the table
never try and grab it. Jump back away from it, let it come to rest, then retrieve it. You might singe the carpet, but believe me, it's better than a nasty burn across the palm of your hand.
