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, itΒ΄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.
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.

POWER switch Battery check indicator When you turn the power on, the battery check indicator lights up momentarily. This is normal. The light tells you that the battery still has life. When the battery becomes weak, the indicator lights dimly or does not light at all. L-shaped stereo miniplug (gold plated) Battery box You can clip the battery box to your tie, lapel or pocket. Microphone jack L-shaped stereo miniplug (gold plated) Battery compartment Microphone Holder clip A Interlock the projection of the holder to the groove on the microphone. B This microphone holder allows you to tilt the microphone 45Â° backward or forward.

After correcting the original service problem, perform the following safety checks before releasing the set to the customer. 1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 4. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. Check the B+ voltage to see it is at the values specified. Flexible Circuit Board Repairing

â¢ Keep the temperature of the soldering iron around 270ËC during repairing. â¢ Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). â¢ Be careful not to apply force on the conductor when soldering or unsoldering.
