HELP! While attempting to repair my 37-665B, my repairman states that raising the volume of the radio results in loud "pops." All the capacitors, resisters, and tubes except the 6K5 in the audio subsection have been replaced. Adjusting the volume doesn't change the loudness of the "pops." What is causing the problem? Your help is earnestly needed and appreciated.
