[Elecraft] KPA500 - linear power supply

[Al Lorona]

One of the inviolable rules in the W6LX shack is: NO SWITCHING POWER SUPPLIES.

Not to make an incendiary statement, but *all* of them generate RFI. Many people 
will tell you that they've never heard RFI from their switching power supplies, 
but often it's just because they don't know what it sounds like or they haven't 
tuned across the right frequency. 


Why raise the noise floor by even half a dB if you can help it?

Nothing beats a old-fashioned, big, beefy, and quiet linear power supply.
