I would just get a cheap bk 465 CRT tester, which can test all voltage crts and only bring $20-40 on eBay. You can usually look inside the housing by removing the rear cover. If you look down at an angle, the original Philco yellow tag will be on it and tell you the model and filament voltage of the CRT. Be careful soldering on these early pcbs. Too much heat and the foil traces will peel off. Check for any cold solder joints on the bottom of the board and make sure all traces are not broke anywhere. These are tricky sets that require patience, but having done a few myself, they're not that bad.
