Well, hopefully it will keep working this time.
I've had tubes that would act funny, that improved very well once I removed the old solder from the grid caps and flowed new solder onto the caps. The 75 tubes seem to be especially prone to this problem. I know your radio does not use a 75, but I've had more than one radio make sounds like a loud thunderstorm due to a fault in the 75 tube. Sometimes, reflowing the solder on the grid cap would fix it; other times, it took replacement of the tube.
