votage Never having had either a broken beeb or a broken cub monitor, I have no idea whether they care about the frequency or not. It's unlikely, but you never know ... One or other of the PDPs used to derive some sort of rough clock from the input frequency. You told it whether it was running 50Hz or 60Hz so it could adjust appropriately. There are (cheap) travel adapters that allow you to plug UK appliances into various worldwide connectors. I don't have one to hand to check, but I do know some of them can cope with a hairdryer - whether that's enough to not catch light when trying to feed an early beeb with the varnish-stripping PSU is not clear to me :-) Antonio
