Did a little more on the Silvertone today.
First I made a new Grillecloth.
I took some leftover fabric from another project and put it on the speaker board, then, since it was way too light I took some Mohawk Van Dyke Brown Toner and sprayed it lightly, several coats until it looked about right.
Installed it in the cabinet and it's an excellent match! Not the same as original but an effective replacement I think.
I also put the speakers back in the cabinet, all except the right tweeter, the wires are supposed to go in front of the CRT mount (before the CRT is installed) so I'll have to unsolder them to do that.
The back I got from Dan is nearly a perfect fit, from the chassis side over it's the same but it's about an inch shorter, so on the right side (viewed from the rear) it ends right at the inside edge of the cabinet. I can leave it alone or I could glue a couple small blocks inside the cabinet so I can attach it.
I also salvaged the Tube Chart from Dan's set, good thing because mine is missing.
I plan to scan it, clean it up a little (though it's in pretty good shape) and reprint it.
If anyone else needs one let me know, should work for an RCA 11 too.
For a set that looked really bad it's come a long way.
Note: the legs need to be put back on as soon as I refinish them.
