Hello all, I hope everyone enjoyed their Thanksgiving! I am working on Howard SG-F same as SG-A. I received radio in cabinete, plugged in and it worked loud and clear. I have wood work to do so took  out chassis, and alas...It does not work. All tubes light normally, all voltages normal, all tubes check good, output and field transformer check good. All wired connections intact. All I get is very, very low hum when ear to speaker. All caps have been changed. Any suggestions?  Thanks  AL
