I, and a couple of other British BC-610 owners run our TXs from 50Hz mains,
in my case the domestic 230 V is stepped down to 110V using what is called a
"site transformer" - designed for outdoor power tools. The only drawback I
have noticed is the occasional loud rattling from the antenna relay when it
is powered-up, presumably its AC solenoid coil prefers 60Hz. Running the
whole TX off 220V would mean a swap of all power transformers and
mains-powered relays in the equipment, so IMHO it's much better to use a
step-down transformer of some sort to do the job and give additional shock
protection.

Note that most of those construction site transformers are actually
autotransformers and don't give any real isolation. But it's true that
a shock at 110V is less nasty than a shock at 220V.

I'd tend to suggest real isolation transformers with electrostatic
shielding, if only because it prevents RF from getting onto your power
line grounding system and causing interference issues and a changed
antenna pattern.
