[R-390] DIY cabinet/shielding questions

[AdamAnt316@aol.com]

Hello everyone. I recently began work on my R-390A and, since I don't have 
any sort of cabinet or rack for the set to go in, I've been toying with the idea 
of building a wooden cabinet for it. I thought that this sort of project 
would be relatively straightforward, but then the issue of shielding came to mind. 
Are the top and/or bottom covers detrimental to the correct operation of the 
receiver? I have the bottom cover and the oft-mentioned "Utah plate," but am 
currently missing the top cover (anyone know of a source for just this one 
cover? Would Fair Radio be willing to sell me only the top one, since the bottom 
one is passable?). While looking through the overheating section of the R-390A 
Pearls of Wisdom archive, I found one post which said that the milspec metal 
cabinet one owner had used RFI screening over all the holes in the case. Would 
it be better to try to restore the top cover, cover the insides of the wooden 
case with some sort of metal screening, both, or would neither be necessary? 
Also, what would be the best way to bolt the R-390A into the wooden cabinet? 
TIA.
