[Elecraft] K1 Power Supply

[Don Wilhelm]

Al,

Check the Specifications section of the manual.  You should find that 
the current draw at 5 watts is less than 1 Amp.  If your K1 has options, 
that current draw may increase a bit, but in any case, a 3 watt power 
source should be more than adequate - actually a 1 amp supply may 
suffice, but if you are investing in a power supply consider allowing 
some reserve, hence my recommendation for a 3 watt or greater supply.  
Resist the temptation to use a wall wart supply - the voltages on some 
of the 12 volt wall warts can be as high as 17 volts - use a regulated 
supply rated at 12 to 13.8 volts.

73,
