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.

2. CAUTION:
Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit. If Main Fuse (F501) is blown, first check to see that all components in the power supply circuit are not defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the power supply circuit to fail.
3. Note:
1. Do not use the part number shown on the drawings for ordering. The correct part number is shown in the parts list, and may be slightly different or amended since the drawings were prepared. 2. To maintain original function and reliability of repaired units, use only original replacement parts which are listed with their part numbers in the parts list section of the service manual.

1 (Unit: Volt) 5.0
2
3 5.0 Power on mode
Voltage
Indicates that the voltage is not consistent here.
5. How to read converged lines
1-D3 Distinction Area Line Number (1 to 3 digits) 3 AREA D3 2 AREA B1 1-B1
Examples: 1. "1-D3" means that line number "1" goes to the line number 1 "1" of the area "D3". 2. "1-B1" means that line number "1" goes to the line number "1" of the area "B1".
1-D3 A B C D
6. Test Point Information
: Indicates a test point with a jumper wire across a hole in the PCB. : Used to indicate a test point with a component lead on foil side. : Used to indicate a test point with no test pin. : Used to indicate a test point with a test pin.
