Hi Thomas,
I'm not sure what your operating style is but if you are looking for 100w on
CW and SSB then I recommend the Gamma Research HPS-1a. I have one and run my
K3-100 with it all the time in a portable fashion. Here is a link to Fred's
site: http://www.gammaresearch.net/
It has a very small

The early Samlex switching power supplies were on the noisy side but they have
corrected that problem years ago. I personally use the Samlex SEC 1235M
switching supply with my K3 and certainly do not get any noise from it.

I bought the Alinco DM-330MW to power my K3. It's pret
Based on my own personal experience, I would recommend a linear supply. I
use the Astron RS-35A. Yes, it is as big as the K3, but it is rock solid,
well-filtered, and RFI-free, and has over-voltage and over-current
protection. In addition, the Astron has heavy-duty output terminals that

Same here - nice quiet PSU. I would buy one again without any hesitation.

I don't like switchers. I have a Diamond GSV3000 25A linear supply.

Same here. I have two of these supplies, and have yet to hear a
