for best noise fit a 1 to 1 220-240/220-240 transformer

only connect the live and neutral to the primary

the secondary fit the live and neutral to your fuse board and the center tap fit to an earth rod and then to your fuse board

this will stop any spikes in the secondary windings as they are lost to the magnetic field

if its as single phase supply a 80-100 amp va transformer is whats needed

you can also do this on an ups with an inverter to stop any noise created by the invertor circuit as the sin wave is created by software

toroidal transformers are the best

unless the power is really bad, you won't need it.

yes, that's the problem with line regulation. to do it correctly it still takes big, heavy transformers. the small regulator still might be ok, if it's only for the computer and XITE. even the one space unit is heavy, though.

Yep, I still have one of these "big" transformers here, built into a rack.
Once it was used on fairs in UK demonstrating Steini software on Carillon DAW machines.
Over 20kilos,- but only 500VA (350W at max.).
Was o.k. for a single core Pentium 4, but today is useless.
It´s specs are impressing nonetheless,- narrow tolerances, very good regulation and nearly undestroyable.
