In all cases, I make certain that the sets I restore are enclosed to NEMA-1 specifications. Back and bottom covers, if missing, are replaced. With missing bottom covers where I do not know how the original was constructed and lack access to a sample upon which to base a design for a reproduction, I have been known to cut a piece of ordinary window screen to size and secure it with staples. In other cases, where an outline of the original cover is visible, I design a cover with the proper shape and an array of 1/4" diameter ventillation holes spaced 1/4". For makes that used slots for ventillation on back and/or bottom covers (Zenith is one), I design the reproduction part to have an array of 1/4"Wx4"L slots spaced 1/4" between slots and 1/2" between rows. Reproductions of masonite backs are under development. I need to find a manufacturer with the proper tooling to fabricate masonite (cutting to size and punching of ventillation and other holes). I'm also researching plastic parts such as CRT neck caps.
