So named because it gets you closer to God.

I once went into radio shack in the US and asked for an extension mains
I lead. got a blank look, so I pointed to what I wanted and learned
I that I should have said power cord.

It was common, in the days of tube-based TV sets, to salvage the power
cord ("cheater") from an old set.  The cord on the set was affixed to the
back cover to provide an interlock so you couldn't operate the set with
the cover off.  The "cheater" eliminated that restriction -- at a bit
of risk to the user.

I don't think the back of our tube-based TV was ever on. While it was
under warranty, service people seemed to arrive monthly. When it was out
of warranty I learned a lot about the practical side of electronics.
Eventually it ran reasonably reliably until the picture tube gave up so my
father and myself replaced the A66-140X

I don't think the UK ever had any tube only colour TVs, they were all
hybrids (tubes for high power / high voltage) and semiconductors. In the
above case all discrete except for one integrated circuit (line
oscillator).

Some of the earliest UK ones were all-valve, Decca made one that was an
absolute monster.  Because they were very expensive and novel, not many
were made, so you may not have heard much about them.  There were huge
problems with stability of the convergence and regular de-gaussing was
necessary (it wasn't automatic at switch-on until later).
