Mic Power supply's a hummin-OK to use a ground lift adapter?

Forums

So there's one and only one thing in the studio here that introduces ground hum.

A power supply for a tube mic.

Everything's on one isolated circuit BTW.

A 3 to 2 prong ground lift adapter will silence this nutty piece o' hummin gear, but is it safe? (This mic will be used for a D/I'd electric guitarist who will be simulaneously playing and singing).

Ground Hum/Power Cond or what?

Hi. I recently moved to a new place with a terrible 60~ hum.

This is not a problem with any wiring I did... this is a problem in the house. I get a hum simply from plugging just about anything into the wall, especially a guitar amp. But I can even hear a slight hum from my computer being plugged in.. so its pretty bad.

Guitar hum. Does this work ?

In mosty cases, i suffer from electrical guitar emating a buzz when plugged in, more so with distortion. While asking the guitarist to turn around and turning off my CRT's does help to a degree, very often the buzz is still dominant.

Just saw this product on soundroom. If it works i cud throw it into my do buy list.

Joemeek VC3, hum and hiss whenever I turn on the phantom

I JUST GOT A JOE MEEK VC3, AND WHENEVER I TURN ON THE PHANTOM POWER, I GET A LOT OF HUM AND HISS. IS THIS DUE TO THE CRAPPY WAL-WART POWER SUPPLY THAT CAME WITH IT? I HEARD THAT SOMEONE WAS EXPERIENCING THE SAME CONFLICT AND THEY PURCHASED A ROLLS PS-12 POWER SUPPLY AND IT MADE THE SIGNAL MORE QUIETER. PLEASE HELP, THANKS.

Hum elimination

Every studio has a certain amount of hum-problems, the more gear the more problems, I suppose.. Especially combining balanced and unbalanced gear seems to generate some problems, you may have outside factors that give you hum and probably a million reasons more. I've been trying to get my studio as quiet as possible for the last days but a couple of (very small) problems remain.
