Yesterday, I finally took the cover off my KPA-1500 power supply, which
has been sitting on the carpet behind my desk for 2 1/2 years. I have a
shedding dog and am not particularly fastidious, so I was worried about
diminished cooling. I needn't have worried - the interior of the supply
Yes, I leave my Power Supply on all the time. I just keep an eye on the

I believe he is talking about PS fans, which is not on the menu. However,
there is a mod kit from Elecraft that includes the resistor. It is very
easy to install. No soldering is required, and the most time-consuming

I went directly to Elecraft with my question. The answer is 6g.
I was told to be sure to use the correct crimp tool for the job. If I

Okay have looked over the posts, but somehow have missed the actual
AWG(American wire gage) SIZE of the stock DC pair? Anyone KNOW this or maybe
even micro-ohm tested (a long shot) it? Voltage drop (ps to amp) divided by
full load dc amps would be close enough.

If it uses a 75 Amp PP connector, my inclination would be to use the

I don't see it documented, but it uses a 75A PowerPole connector. Cable
