Just to be clear on this, a "ground lift" switch disconnects the
chassis ground from the signal ground. It does NOT remove the chassis
ground, which is what you do if you plug a 3-pin plug into a 2-pin
socket!.


The general advice on this is that if equipment is shipped with a 3-pin
plug, it MUST go into a 3-pin socket (UK and US codes differ slightly on
this point).

There IS a risk (albeit VERY slight) of electric shock in the event of
an internal fault which allows the chassis to become live, if you have
disconnected (not lifted!) the Ground.

The proper fix here is to figure out why you have a ground loop. Is the
equipment sitting in a metal rack? That is often the cause of such
problems.

I would disconnect all equipment from the "outlet" apart from pre-amp,
power amp and TP and see if the hum persists.
