I was talking to Paul at TT service recently about a problem with my
Pegasus. He asked about my power supply. I'm using my Astron RS20. He said
that that really doesn't have enough power for the Pegasus.  My impression
is that perhaps the Pegasus is a little less efficient than other 100w rigs
so it draw a little more current. I'm going to switch to my RS35 supply for
the Pegasus, but I will install a 20A magnetic breaker for overcurrent
protection, since the Pegasus doesn't really have any.
