My tubes arrived today and the used 6A7 i got performs well in the radio without that whistle. Its a philco like the one that was in there that i nipped off the tip.. The tube that was disagreeing was an RCA brand, who knows what the difference was...
So ill send it through an alignment and see how it goes..
