I was at a local estate sale last Saturday and found this beautiful vintage EICO Decade Resistance Box to restore.
The steel box was a bit rusty, and it was caked in dirt, but after some cleaning it turned out that the aluminum faceplate was in great shape. I used Evapo-Rust to remove the rust on the box and then spray-painted it a nice black. Next, I sprayed the switches down with DeoxIT and tested all the resistors. Surprisingly, most were still in spec, however two were open, so I cut those out and soldered in replacements. While I was at it, I added banana jacks; now I can use all of my test cables with it. I also traded the rusty screws for brass, because pizazz.
