FWIW, recall a post (I could be wrong but thought it was here) where hammer control switches were receiving 240vac. This was not a super old machine.

?Well: the diagram shipped with the machine says the controls are at mains potential and doesn't show a traffo, the contactors have 220V coils, and physical inspection shows that there isn't a traffo ... pretty conclusive in my book. It would be quite tricky to get a probe onto one side of a contactor and I don't feel like disturbing everything. The 500mA fuses have no bearing on the voltage, and are appropriate to protect from a coil failure.
On this machine (made in 1996) all the controls are on the body of the machine and the wiring is internal, so there is no violation of safety standards.
Taking the cover off had an unexpected benefit - I spotted that one of the caps is becoming rather obese and may soon exceed the ability of its casing to restrain its innards. A bit of preventative maintenance is in order.
