Well I guess I do not understand one thing. I now know that the tube heater line is getting too much voltage. The diagram shows the output of the rectifier going to a 1,800 ohm res. then to the heater of the 1Lb4. That is the way this set is wired right now. Do I just need to jump up the res. to lower heater volt. or does this tell me that something else is going on?
