Your test says it all. Somewhere vic the 1stDet/Osc circuit. Check coils for continuity, I don't see where the resistance values are listed.
Also could be something making contact that is not supposed to.
Are the tube sockets OK? Not corroded, dirty, bent, etc...
Although I have never heard of one, could it be a "noisy" 24/27 tube?
Next would be the mica caps.
