Thanks, but been down that road many times now hoping I will find the problem.
Did find a bad tube socket on one of my 10 tube zenith that I am having issues with static on warm up.
Replaced the 6V6 socket and it helped a lot, but still have some static on warm up.
So I know cleaning the pin holes helps, if they thru holes. My 10 tube sockets are blind, so very hard to clean.
When the radio in question is on station, the noise goes away. Just between stations.
Hope this helps!
