To go along with the other thousand questions I've already asked, I have another.
My plan for the Beta 22 is now going ahead. I am slowly gathering the materials I'll need for the project, and I've come across a great looking all wood chassis. It's essentially the same thing that amplifiers came housed in during the 60s and 70s. I know that Dynaco had one just like this. It's basically a four-sided box with a removable front and back panel, which I plan to make from thin MDF and plexiglass.
This will have no metal in the chassis aside from the screws holding the panels in.
I want to integrate the Beta 22, Sigma 22, and Buffalo 32 into the chassis with all three transformers inside. It'll be a bit of a tight fit, but all should work out ok.
My idea for shielding the components from the transformers is to build a faraday cage inside the chassis, surrounding (but not touching) only the transformers. Will this be sufficient sheilding to minimize interference? I'd have to connect the cage to earth ground of course.
And then, how would I connect pin 1 of the XLR (hypothetically, there will be no actual XLR, just internal wiring). I read in another thread that a metal chassis should be connected to earth ground and signal ground. In this case, presumably not to the cage as it would introduce badness into the ground reference.
Any tips for how I can pull this off? Also, will high frequency (4kHz) switching from an ElectroLuminescent inverter cause problems in either the cage or the unshielded part of the enclosure?
