Admiral, check my post on the model 77. Below the pictures is Ron's link to Philco replacement speakers. It appears both the 76 and 77 use the same replacement. Ergo I assume my "H" original would work for your 76. Ron can set me straight if that's wrong. Also some other parts are used in both sets. I'm going to part mine out as the cabinet is beyond salvage. Too bad the legs are different.
