hey guys, so a little update. I am fiddling with the jumpers to see if the heater settings are correct. But I am getting some strange voltages. When jumpered for 6.3 V, I am getting 10.97V on the right (damaged) pin 4 and 5.5V on the left pin 4. when checking the jumper test point I am reading 5.5V.
I can only guess that the 6.3V jumper position isn't working properly and more of the voltage is going to the right heater. any suggestions? what would cause the uneven distribution of voltage to the heaters? thanks!
