When I had my 240V / 30A circuit installed for the SB-220, the electrician
asked whether I wanted a 3-prong or 4-prong outlet. I chose 4-prong since that
seems to be the modern standard. That meant replacing the 3-prong plug and
power cable on the amp with a 4-prong, though the center tap isn't used on this
amp so the neutral wire isn't actually connected to anything in the amp.

Yep I remember a dryer I bought in the late 70's was wired that way, 240 to
the heating element and the motor and the rest right to a ground lug. Since
my current dryer, a 10 year old Kenmore, also uses a 3 wire cord/plug it may
be the same and I'll look the next time I pull off the back panel to vacuum
and collect loose change (-:
Im certainly not going to sleep over it as millions of dryers didnt kill people.
