50s Japanese am/fm tube dual speaker radio

[maxhifi]

PROGRESS!
I decided hey let's try swapping the 17EW8s and see if anything changes (both tested good), suddenly the volume on FM massively improved, and the radio actually sounded good. I cleaned the pins and sockets really well, and put the tubes back in their original locations, and the radio works 100% better, lots of volume and much more sensitive. These have got to be the worst tube shields I have seen in my life, they're made of thin sheet metal and fit so tight they have to be practically forced in place. Anyway the radio alignment is now messed up (oscillator and RF trimmer), since I was working on aligning a broken radio before, but finally I see light at the end of the tunnel with this one...
