Not sure if I understood you correctly.
So in my amp I simply connect pin 4 and 5 to the ground, right?
And one more question. My amp is almost finished. What pre-cautions I should take before plugging anything into it?
The only thing I can think of is to measure both AC and DC voltages on the output.
