I needed the manual immediately and I got it immediately. I couldn't find this manual anywhere else on the net. The site was easy to traverse, and the price was very reasonable. I'll definitely be back for any future needs.

I received a good service manual, with good resolution. Improve the instructions for the purchase because they are not well understood.
For the rest, so good.
Thanks Angel.

Very good documentation for the Grundig 2077 model (as well as similar 800/900/1000 series radios). The first two pages are a summary of reception specifications and output capability. The third page is the tuner dial indicator and dial cord routing diagram. the final ~5 pages are the schematics for the various models (including 2077). The scan quality of the schematics are good, adn can be easily read if zoomed in. The documents are in German, not English as stated. It would have been nice to have the tuning sequence and settings, and some trouble shooting materials... or component and wiring map.

SECTION 1 SERVICING NOTES
This set detects the rotation of GEAR (PH) using the PH701 (photo reflector). The PH701 is mounted on the MAIN board, and therefore the GEAR cannot be detected with the MAIN board removed. As a result, the motor cannot be controlled, causing malfunction. Further, the S702 (FWD/REV switch) is also mounted on the MAIN board, and with the board removed, the mechanism position cannnot be detected and the operation is not changed over. Therefore, when the voltage check is executed with the MAIN board removed, follow the procedure provided below.
Note : Do not move the S702 swithc position when removing the MAIN board. If it is moved, the set will not be changed over to the selected mode. In this case, reconnect the MAIN board to the set and retry the work from the beginning.
1. Setting 1) Refer to �3. DISASSEMBLY�, and remove the cabinet and open the MAIN board. 2) Connect the MAIN board to the M901 (motor) and PM901 (plunger) using jumper wires. 3) Short the ATS terminals. 4) Press and fixed the S701 (CASSETTE HOLDER). 5) Supply 1.5V to the battery terminals � and � using a stabilized power supply. 2. FF, REW Modes 1) Input a square wave to the TP35 (PHOTO IN) and TP23 (GND). (See figure below) 2) Press the S704 (STOP) for selecting STOP mode. 3) Press the S706 (FF) or S707 (REW). 3. PLAY mode 1) Input a square wave to the TP35 (PHOTO IN) and TP23 (GND). (See figure below) 2) Press the S704 (STOP) for selecting STOP mode. 3) Press the S705 (PLAY). (Each time the switch is pressed, the mode is changed over.)
