You still need a bigger Power supply, The Pyramid brand has a tendency to
advertise more than what they actually put out. I had the same problem.
Invest in a nice 20 Amp Astron, or tripp-lite power supply and that will
take care of things for you. You can always get a good deal on one used if
you look. Qrz.com classifieds, Qth.com classifieds, etc. Good luck!
