I'm in the process of making an integrated dual mono amp with circuit boards care of ESP.
As the design of the beast in question entails there to be 3 toroidal transformers inside the same box as the pre-amp and power amps I want to employ internal shielding as well as earthing the case.
I've already decided to shield the pre-amp in it's own aluminium box inside the main case as this is probably the most prone to interference. I'll also be using a "zero volt line" - as described on the ESP website.
One final thing I was wondering about was sheilding the toroids?
Would it be benificial for me to source individual boxes for them for inside the main case or could I wrap foil around them or would this break the continuity of the lux lines?
Any help would be appreciated, also ideas how to reduce any kind of interference.
