I found that my amp5,
Right sound go to left speaker and left sound go to right speaker!!!
I reviewed the pin number from assembly instruction,
I found that J8 pin 2 is "INV1 to TA2022"
pin 3 is "input 2"
pin 4 is "input 1"
pin 5 is "INV2 to TA2022"
So! instead of 21st step in the instruction "Solder jumper wire on J8 from pin 2-3 and pin 4-5..."
I think we should solder pin2-4 and pin3-5!!!
Or we will have input 1 to output 2 and input 2 to output1 !!!
I found many photo in forums with pin2-3 and pin4-5 soldered together,
Haven't you guys found that right sound go to left speaker and left sound go to right speaker?
by the way...VERY clear and sweet sounds, Thank you, Jan!
