I just purchased a used Dyna 400 and need some help. I don't have a
parts list or even a schematic. So, my problems are compounded. But
here goes. There is a small circuitboard mounted on the front side of
the huge transformer. On this board a 2 large power resistors, R307 &
R308. I need to know what the resistance values and watt ratings are
for these 2 resistors. Can anyone help??
