this monster amp is causing headaches,
puts out 1900 watts into 2 ohms!
all the output transistors and drivers have been pulled and checked, but when power is applied the transistors start to get hot in a hurry til the fuse blows,
so we are working backwards, no voltages on the schemo does not help,
the TIP31 (red arrow) was not stuffed into the board, and the resistor (circled in red) is 0 ohms (jumper)
this is apparently an option on the board, we tried putting in a TIP31 and taking out the resistor but no joy,
my question is <what is the function of the TIP31 transistors and what kind of voltages should be present?>
thanks for any help! the 340 and 350 surface mount transistors have been replaced already,
