For sale is a vintage General Radio Co. Model 814-A serial no. This vintage piece of test equipment was produced around 1937 for lab use. It has three mixed brand type 34 vacuum tubes. This piece is in decent condition for its age with many signs of wear and age. The gain knob had a piece about 1-1/4 wide broken out of the base when I acquired it. Luckily, the missing piece was inside, and I was able to glue it back together. The cracks are just faintly visible on the front (see photos). There are a couple small holes in the front right above model/serial numbers. I’m not sure if there is a badge missing or these holes were for. Otherwise, this piece appears to be complete. Nothing is obviously missing or altered. The cabinet is intact but most of the original finish has worn off. The underside of the top appears to have some staining from moisture. This staining from moisture damage covers about half of the paper schematic/instructions. The cabinet is just slightly loose at the bottom left corner joint (see last photo). Electronically, this piece appears to be pretty clean and in good condition. This piece originally operated on batteries. Please see all photos for condition and completeness of the item. I can provide additional photos upon request. Cabinet dimensions are 12-1/4″ wide (excluding handles) x 12″ deep x 8 tall.
