Universal Radio has a very good price on the 23 AMP version for $89.00
I bought an Astron switching power supply about four years ago when I got my
Omni V. I have looked at it with a scope and under a heavy load, such as key
down it has a slight amount of switching noise above the HF range at about 150
Khz. I set up a scanner at those frequencies and with the squelch off I could
hear a slight amount of noise out to about a 20 foot distance. So if the police
ever come to my house and get within 20 feet of the power supply under full
load they might hear it. Other than that its a nice power supply. However I
think Samlex has the state of the art in switching supplies. CQ did a nice
article a few months ago when they reviewed the Jupiter and gave it high marks.
If I were buying a power supply today I would get the Samlex. With a switching
supply you get a light weight which means you can safely stack more Ten Tec
radios on your bench!
