[Elecraft] Fusing the K3 Power Line

[Matthew Zilmer]

Hi Lee,

The manual (rev D10) doesn't really say 25A fuses, just that the power supply should be rated 25A and that two fast-blow fuses should be used in the supply cabling for protection.  I use 30A fast-blow fuses, one in each of the pos and neg lines.  Power comes from a battery, and the battery is solar-charged.

Reading the manual....it says that two 25 amp fuses should be in both the positive and negative leads going to the K3 from the battery.  Now, what about AC supply like and Astron 35M.  Should you also have the same thing - two fuses inline from the PS to the K3.  The manual talks about a "battery" but doesn't address that specifically (or you could infer) for a AC power supply.  Or, am I just loosing my mind?

 In our day and age it seems that Common Sense is in short supply.  If you don't have any Common Sense - get some Common Sense and use it.  If you can't find any Common Sense, ask for help from somebody who has some Common Sense.  Is Common Sense divine?

Common Sense is the image of the Creator expressing revealed truth in my mind.
