I run my K3 from a Pyramid ps21kx power supply, a linear supply which has done a great job for a couple of years. But it has a fan, and when there is nothing going on in the shack, the fan is audible. So I got a temp control gadget on eBay for 15 bucks shipped from the U.S. I opened up the power supply. I opened up the supply, cut the hot lead to the fan and brought out a little twisted pair to an R/C connector so I could control the fan with the temp gizmo. I stuck the sensor next to one of the power transistors with some picture-mounting gum. Now all is quiet until I transmit. Then it kicks on and stays on (you can set both in and out temperatures), so everything stays nice and cool as well as nice and quiet. If you're looking for a good power source for your K3, I recommend the Pyramid, and I also recommend this simple mod.
