It looks like there was a "pilot error" in your CAD drawings regarding C6 and C7 and their polarity thereof; (LOL) and magic smoke would result...

Also, why all the bother of doing a 21st century PC board when a simple time period correct 8-way terminal strip will do the same function (and terminal strips were how it was done; construction at the time) to somewhat maintain the authenticity of it? How far does one go with a restoration or a total re-engineering of this type of vintage gear? In the 1940's when this unit was produced, man-kind had no idea of how PCB materials like FR-4 would eventually revolutionize the electronic world of construction.
