I meant no offense, I had misunderstood your original post and thought that you had already replaced this crispy resistor, and then it blew up again.
if you're checking diodes, it doesn't sound like you know the problem. there are only a handful of diodes in that amp and none of them would cause R40 to fry.
Do you have a variac? why not slowly bring the power up and see if the amp pulls too much current, or if R40 drops too much voltage?
what have you checked?
