[Elecraft] Highest power supply voltage for K2?

[Hisashi T Fujinaka]

I worked in the semiconductor industry and I remember frying a bunch of
chips when I reached a knee in the current draw. You can increase the
voltage until something breaks down, and then you're hosed. Lots of
current flows and your semiconducting device is no longer conducting at
all since you let all the magic smoke out.

I'd suggest the correct batteries, but I worked in a ham radio repair
shop years ago and I know how *(@#*&$ cheap hams are so I know telling
you to pay any extra to use the correct batteries will fall on deaf
ears. :)
