[Elecraft] Items you think you can depend on

[Don Wilhelm]

I was at the Shelby, NC hamfest this weekend, and we had the KPA1500 for 
the Elecraft booth.
I caught myself several times referring to the line voltage required as 
220 even though I know better.
My age is showing.

But I do know that if one is operating the KPA1500 in a commercial 
building with 3 phase service, the voltage is 120/208.
The KPA1500 power supply is a switcher, and most switchers can tolerate 
a wide variation in input AC voltage.
