I have a 38-7X Console radio which is missing the speaker. I have a speaker for a 38-38X however it has a different output transformer attached, and the speaker is stamped as a HR-20 and is driven by a push pull output tube 1J6G. The schematic / parts listing for the 38-7X calls for a H 31 speaker driven by a 6F6G output tube. Is there a way to modify the HR 20 or use a totally different speaker?
