Hi, what I'm seeing on the schematic is one wire from the output transformer goes to B+ and the other goes to the 7B5 plate terminal. You haven't mentioned the value of the cooked resistor but I'm assuming it is either 220k or 220 ohms. If it's 220K then you have to tell us which end is connected to the 7C6 plate.
