[Amps] FW: RFI Question

[N7HIY]

put ferrites on the speaker leads first, as many turns thru core as 
possible...will be more more effective.....clip on ferrites are not very 
effective...made for those looking for placebo effect...
search web for "shielding paint"...lots of links and paints for sale...your 
paint mileage may vary.
