If you know how to solder, and can learn to read circuit diagrams., these sorts of sets are not too bad to work on , though because it's an AM/FM job you won't be able to align the FM side without some special equipment. The service info from that era is laid out pretty nicely, Philco was kind enough to break the circuitry down into blocks, sometimes with potential faults listed for each. I don't agree, other then pontential trouble with the mica capacitors in the I.F cans these sorts of sets are good for practicing restoration skills. One more thing, although you probably know this, the original record changer is missing, but once you figure things out you could probably use the amp with a different one, which is what it looks like you may have been trying in the picture. You could probably find a replacement unit out of a junker, if you really want the unit all original. Whatever you do, do not try stripping and refinishing the cabinet doors, the marquetry pattern is a faux finish.
