Hi Edward ~ Your Admiral is more likely late pre-war; ca. 1939 to 42, or early post-war; ca. 1946-1947.
The symptoms you describe are typical of this technology when it ages, and are: Hardened rubber on the idler wheel (turntable noise); Dead electrolytic capacitors, two to three of these will be found in need of replacement (loud hum and garbled sound). This is a job for a soldering iron, and the correct types and polarity will be needed. These are available. If when you say "the music sounds garbled" you mean music from a record and not from a built-in radio, then it's a small miracle that your crystal cartridge might actually be good. 99% of these are found dead or substantially diminished in unrestored phonographs of this era. The fact that there's a set screw for the stylus indicates that yours still has the crystal cartridge. These can be rebuilt with a new element if needed (some of the distortion can be from the cartridge), or replaced with a more reliable type of cartridge and stylus. The unit may need some other minor work. Usually motor bearings, idler wheel arbor & bushings and platter bearings need de-gumming and new lubrication, and if it has a changer, these usually need some attention as well. On the electronic side, the power cord may be brittle if it's original and certain of the "paper" capacitors will likely benefit from replacement as these get electrically leaky and can also contribute to distortion. I don't know who in Portland works on antique radios, but I know you can find someone through the radio collector community out there or a museum. If that fails I restore these types of items but you would incur shipping charges in addition to the usual parts and labor. Good luck with this.
