Picked up a Mooer Macro Power S12 a few weeks back to replace my Palmer PWT 05. I noticed a distinct hum coming from it, even without pedals plugged in, so the dealer replaced it for me. The new one still hums, though not as bad.
Today I borrowed my bass player's T.Rex Chameleon and I ran the three of them side-by-side, at first in our rehearsal space and then at home.
I'm getting hum from all three, the worst culprit being the T.Rex. The Mooer has air vents on three sides, and the noise emanating from it is audibly different in pitch depending on if you're listening to its covered or ventilated sides. The Palmer's- the cheapest by far of the three - noise level is almost unnoticeable unless you press your ear to to. All three units have isolated outputs.
Now, I suspect part of it is due to the very old wiring in my somewhat old apartment building. But it made me wonder, when people say a power supply is quiet, do they mean "dead quiet at all times" or "doesn't cause excessive noise when pedals are plugged in"? Furthermore, I thought about sending the Mooer back and replacing it with a TrueTone CS12, but now I'm not so sure that would actually help.
