Hi Doug
Your unit probably has an "INTERNATIONAL PHILCO" decal, yes? Those big modified Philco radios with external amplifiers and (sometimes) phonographs were a joint venture of Philco and IBM! These were produced for schools and industrial use.
This is mentioned in the History section of my website, with a couple of photos.
I've never heard of a Philco home radio that used a Type 50 or 81 tube.
