You'll get a lot of comments on this. Many like switchers. I
personOally prefer the old analog transformer supplies. Many swichers
are clean, some are not and put out spurious birdies in the ham bands.
Some have a fan that runs continiously such as in my mfj switcher. I
tend to leave my rigs and supplies run 24 seven, so I see no need for a
fan running, they shoould have put some kind of temperature control.
I've got a couple Astron 70 amp standard supplies which i run a 2 meter
and an hf amp on. Very heavy, but my preference. Also, I know how to
repair standard regulated supplies, switchers are magic!!
