I am only search for 5 Minute, by it in 5 Minutes to and get ist in few ours! Best i found in the Internet and my Amplifer is repaired as well! Thank you
I found the manual to be clear concise and complete. It was of immense assistance when removing the unit as the unit was over 22 years old and the wiring diagram was unobtainable from the manufacturer. The exploded drawings were clear as were the instructions and labels.
I will highly recommend this seller. They are honest, accurate, fast and responsible.
