That cabinet is a 37-10X. I guessed at the chassis being a 37-11 based on the tube locations. The photograph in our
Philco Radio Gallery (bottom of our Home page) is a twin to your photograph. The chassis was 'compromised' through the years. Not uncommon during the WW2 years. "I can't afford anything new. Just find a way to make it work" was a common lament to sales persons or service techs. It is a 6F6 push-pull output, so it should sound good when restored. It's a far way from there now.
Incidentally, the 37-9 through 37-11 all had similar front layouts but, based on your photo and our Gallery I am reasonably certain you have a 37-10X and 37-11 chassis. Wouldn't be the first time inventory dictated 'cross-utilization' resulting in the occasional "PhrankenPhilco".
Service detail is available in the Philco Radio Library.
