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.
1. Input the 98.1MHz/55dBμ(1kHz 30% MOD) signal. SSG 2. Adjust the outputs to �18±3dB by VR102 when the SG output is set to �20dBμ. AC volt meter 1. Turn off and on the ACC switch twice, while holding the buttons of power switch and CD eject to make the unit the test mode. 2. Set a universal timer to TP101(T-BASE), adjust TC201 so that a reading of the meter is 0±0.1 sec./day. Chronometer
