Hi All,

Excitement in the lab last night! - I left the 2113B running on the bench
whilst I went to make a cup of tea (yep, British) only to return to a room
full of smoke.

Turned out that the 240 volt rated 0.22u surpressor capacitor (mounted
across the live and neutral pins on the mains socket) had decided to give up
the ghost. No real damage done - just a bit stinky and a bit of smoke
damage.

The machine had run just fine for about two hours before the cap decided to
break. This has happened to me before on another piece of ageing
electronics - it is probably worth checking all old electronics for this
type of surpressor capacitor and replacing them BEFORE turning the equipment
on.

Hope that this is of help to someone.
