Heath product with 120/240 slide switch instead of diff. wiring

[Edwin J Forwood]

Take a look at your desktop computer.  Many are equipped that way.  It is
especially if the units were designed for marketing in both US and
Foreign markets where 220V (often 50 Hertz) is the norm.  Frankly it
would have been nice if that were the norm here.  Think how much lighter
the old boatanchor  or modern amp would be with a transformer that is
half the size of the one in it!
