I have never worked on one of these, and told him I would ponder the problem before coming over, by checking the schematics. According to him, the only issue is now, when he turns on the filament power, the B+ comes up also, without keying it. Before I download a schematic and bring out the Ouija Board, is anyone familiar with this problem and knows exactly what is wrong? Do I need to get more specific info on this turn on problem?
