Good point! I'm definitely going for a two box approach as I stated in an earlier post. I will use a couple of enclosures from DIYenclosures.com. The power supply enclosure should arrive tomorrow. Should keep me busy this weekend :-)
Yesterday, I was at my local dealer (Jeff's Sound Values) and the owner showed me a sheet of special material that's supposed to filter EMI/RFI emissions. This adhesive material can go inside the chassis or wrapped around certain parts such as analog and digital connections. It's non conductive. I forgot to ask the exact name of the thing, but I'll research it for my project. tyler_durden;194776 Wrote: > Unless you box it up in mu-metal, the metal case will not prevent > magnetic fields such as those from that big power supply transformer > from flying about.
