nothing but GOOD things to say about the Moseley 9003's!
having random, brief "blips" and dropouts? A few years ago, I
posted about units at my (soon to be former) employer doing
that. The fix is actually VERY EASY... just install capacitors
across the 7805 regulators inside!
a 10uf electrolytic with a .1uf disc across it. It's been
"bulletproof" ever since.
regulators will oscillate if they don't see at least .1uf on
the outputs, and if they do, they do all kinds of strange
things to the circuits they powering!
