[Elecraft] KPA500 Power Switches

[Alan Bloom]

10 watts is 240 watt-hours per day, or about 3 cents, depending on your
local utility rates.  If you use the amplifier once a day, you have to
decide if it's worth 3 cents not to have to reach around behind the
amplifier to turn it on when you start operating and then reach around
again when you finish.

If you typically go for weeks between operating periods then it
definitely makes sense to turn it off.
