[time-nuts] Anyone (ideally in the UK) got a spare rotary knob for the 5370B TI counter?

230VAC +10% -6%, so 253 is the upper limit.  248V is not unusual as for historic reasons some parts of UK still actually supply 250V ...

When  we "harmonized" our mains with the EU, we changed the specification from 240V +/- 5% (I think) and didn't actually change any equipment.

Happy New Year
