Hi, folks - If you please, I am looking for recommendations for a PS
that will provide the usual 12 or 13.8v, about 5 - 7 amps be plenty.
Love to get rid of the myriad 500 ma wall-warts. *I'd rather not have
it be too expensive, but it would be nice if it didn't send spikes,
blow up or cause hash or electrical hum. *Any thoughts? *There is a
plethora of manufacturers and models, reviews are all over the place,
I have no idea which ones are OK. *Pyramid makes a 5-amp job that
would be great, if it's any good. *I also see Radio Shack PSs at about
twice that current. *Would a switching PS be better?
Thanks in advance ~

I use an Astron switch mode supply. *It makes no noise. *It makes no
heat. *Linear supplies waste electricity.

No hash or other electrical noise artifacts?

None that I've noticed. *These are specifically sold for Amateur Radio.
* From what I've heard the Astrons and the MFJs are both electrically quiet.

Thanks - interesting. I'll look into those too.
