Very helpful and complete manual. Maybe only one negative is schematics have sometimes unreadable name of the parts. But it's not a big problem.
 ;
Excellent high quality schematics brought my old Heidelberg back to life. Fast download at a reasonable price. Thanks.

This document is just what I was looking for, it´s very useful, it contains adjustment procedures for the final stage of the power amp and also
has a complete wiring diagram and description of the main semiconductors used in the design.

Dear Sirs,
Thank you for the fast support, the manual does provide all necessary information to repair the radio. All schematics are in a good quality for reading.
The manual fits 100% to my requirements as a technican.
Kind regards Thomas

the big video recorder format s-vhs many features delicate in loading system of the cassette. Such machines are no longer manufactured, it would be too expensive.

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.
