HI

I was wondering in general, how best to create some VERY effective
shielding between some equipment

for example, I wanted to stack my powersupply ontop of a tuner

while each are in metal enclousures and properly"" grounded i wanted
to go further


what is the best way?? would a thin sheet of lead (i'd encase in a
rubber coating) or a sheet of copper?


or would the only way be to say get some copper tape and wrap the unit?


thanks
