50s Japanese am/fm tube dual speaker radio

Yes, it's a little tiny sub chassis. The voltage amp is a 12AV6 and the output is exactly a 35C5. The schematic is glued to the bottom of the radio. The dial light comes on strong when you first turn on the radio, and then extinguishes. I am quite sure it is a neon light, but it's the physical size of a normal 47 pilot light - something may be causing low B+, which may be responsible for the distortion on FM. The 17EW8 is a weird tube, I don't have any spares on hand. The little speakers actually sound pretty good on AM, I am looking forward to figuring out why FM isn't working properly, hopefully it is something simple like bad filter capacitors causing low B+.
