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. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
