Hi ODPILOT,
Octal tube sockets are common and available on eBay. I have not bought them, but I understand that quality of some is hit and miss. Replacement is not difficult, just make sure that you don't "mis-wire" by connecting connections to the wrong pins. Take pictures and get the schematic. Attached below is the spec sheet for the 35L6 from RCA, with the pin numbering from the bottom view of the socket:
Also attached is a link to the schematic for your set:

You can try to tighten the pins of the existing socket by wedging a jeweler's screwdriver, pick or other small tool between the contact and the cavity that it resides in. Then use Caig DeOxIt D5 contact cleaner on the socket. Be sure to thoroughly dry the socket before reapplying power.
This set utilizes a voltage doubler circuit which doubles the power output for the 35L6, compared to the traditional half wave rectifier circuit used in the common "AA5" radios. the drawback of the voltage doubler is the requirement for AC, but since this is a radio-phono, AC is needed anyway for the turntable motor. The voltage doubler and 8" speaker make this a rather good performing set.
Hope this helps.
