Providing the manual works fine, quickly and without any problems for an acceptable price. After printing the service manual it took me only a short time to repair my carradio from Clarion. Thank You! Greetings from Heiko

I was searching a way to modify the original phono-in entry (for connection of vynil disc player, with RIAA equalization) to a line-in entry (for connection of modern analog entries, eg. ipod, mp3player).
This service manual gave me the correct hints.
It contains very useful infos for repairing and modifing the hi-fi, such as disassembling instructions, block diagrams, schematic diagrams, PCB prints, replacement parts list.
Very good!

DESCRIPTION OF SCHEMATIC DIAGRAM
SAFETY NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE REPLACING PARTS. 2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING.
NOTES:
1. The unit of resistance �ohm� is omitted. (K = 1000 ohms, M = Meg ohm). 2. All resistors are 1/16 watt, unless otherwise noted. 3. All capacitors are µF, unless otherwise noted. (P = µµF).
VOLTAGE MEASUREMENT CONDITIONS: IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH �å� ( ) ARE IMPORTANT FOR MAINTAINING THE SAFETY OF THE SET. BE SURE TO REPLACE THESE PARTS WITH SPECIFIED ONES FOR MAINTAINING THE SAFETY AND PERFORMANCE OF THE SET. 1. Voltage in parenthesis measured with no Signal. 2. Voltages without parenthesis measured with PAL Colour-Signal. 3. All the voltages in each point are measured high impedance voltmeter.
WAVEFORM MEASUREMENT CONDITIONS: SERVICE PRECAUTION:
THE AREA ENCLOSED BY THIS LINE ( ) IS DIRECTLY CONNECTED WITH AC MAINS VOLTAGE. WHEN SERVICING THE AREA, CONNECT AN ISOLATING TRANSFORMER BETWEEN TV RECEIVER AND AC LINE TO ELIMINATE HAZARD OF ELECTRIC SHOCK. 1. Colour bar generator signal of 1.8V peak to peak applied at Base of Video Buffer Amp. Q203. 2. Approximately 4.0 V AGC bias.
