Right. And tranformers should not be necessary if you follow the 
simple and inexpensive techniques in my RFI tutorial -- bond all the 
gear together with big copper, plug everything into the same outlet 
(or outlets in the same quad box), and use cable for the 
interconnects that has a beefy copper shield (like RG58).
