Hello List:

Apart from the fact that they're 2 basic types of power supplies(linear, and "switching), I know very little about their relative merits/shortcomings except that the latter type seem to be much less expensive, smaller, but perhaps at the price of a little more noise.  It seems that many people on this list use an Astron supply providing from 25-30 amps.

I could use a primmer/tutorial on supplies, and the practical reasons for  preferring one type over the other.

73,
