[Elecraft] Power supply and fuse recommendations for K2

[Don Wilhelm]

That Smartcharger article is on my website www.w3fpr.com.

Steve,
Looking at the end of your post, I see that you currently have a 1 amp 
fuse which is too small.
Your 2.4 amp power supply is OK if you are limiting power to 5 watts, 
but if you want to run 10 to 12 watts (how about SSB on peaks) the power 
supply should be increased to at least 3 amps.  I usually recommend a 6 
amp supply at 13.8 volts.

73,
