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.
 ;
THIS MANUAL IS VERY GOOD AND VERY CLEAR
PLEASE NOTE IT DOES NOT CONTAIN THE SETUP INFORMATION TO ALIGHN THE GEARS IN THE CD MECH IT DOES SHOW ALL THE PARTS AND THEIR LOCATIONS .

Check points for each error
(1) Spindle start error 1.Defective spindle motor *Are there several ohms resistance between each pin of CN201 "5-6","6-7","5-7"? (The power supply is turned off and measured.) *Is the sign wave of about 100mVp-p in the voltage had from each terminal? [ CN201"9"(H1-),"10"(H1+),"11"(H2-),"12"(H2+),"13"(H3-),"14"(H3+) ] 2.Defective spindle motor driver (IC251) *Has motor drive voltage of a sine wave or a rectangular wave gone out to each terminal(SM1~3) of CN201"5,6,7" and IC251"2,4,7"? *Is FG pulse output from the terminal of IC251"24"(FG) according to the rotation of the motor? *Is it "L(about 0.9V)" while terminal of IC251"15"(VH) is rotating the motor? 3.Has the control signal come from servo IC or the microcomputer? *Is it "L" while the terminal of IC251"18"(SBRK) is operating? Is it "H" while the terminal of IC251"23"(/SPMUTE) is operating? *Is the control signal input to the terminal of IC251"22"(EC)? (changes from VHALF voltage while the motor is working.) *Is the VHALF voltage input to the terminal of IC251"21"(ECR)? 4.Is the FG signal input to the servo IC? *Is FG pulse input to the terminal of IC301"69"(FG) according to the rotation of the motor?
(2) Disc Detection, Distinction error (no disc, no RFENV) * Laser is defective. * Front End Processor is defective (IC101). * APC circuit is defective. --- Q101,Q102. * Pattern is defective. --- Lines for CN101 - All patterns which relate to pick-up and patterns between IC101 * IC101 --- For signal from IC101 to IC301, is signal output from IC101 "20" (ASOUT) and IC101 "41"(RFENV) and IC101 "22" (FEOUT)?
