 I've a 91b that is blowing open (well, perhaps a bit strongly worded) the
R4 resistor on the mains board. Its one of the surge resistors in the step
start circuit. It is in series with a 2A fuse which does not open, only the
resistor which is a 10 ohm 15W resistor. I've replaced it with a new one
with same results. Wonder if anyone can point me in the right direction to
fix this problem. I've this same question to the folks at Alpha.
