In general, is it better to run a receiver off a good external DC power

that I might get less noise using an external DC power supply, but what is
the general concensus here? Thanks.

I find batteries to be the best results. 'Course, that is not very practical.

I use a cheap wal-wart, but I cut the wires and put a capacitor in the circuit, that
seems to help a little. (Had at one time a HUGE capacitor, but it was too much
trouble to carry around)

I suppose it all depends on how the respective power supply is built and how
OLD it is. Electrolytic capacitors dry out over time, (especially older tin-can
ones) which I believe explains the "hum" often heard in antique radios. As
equipment ages, I believe an external supply could help in this area.
