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.

2-2 Tracking system check. Check the TE waveform at pin 15 on IC1.
If the waveform shown in Figure 7-3-1 appears and soon after NO DISC appears ? No "Initialization" is possible, but play is not possible ? No Yes The tracking servo is not activated. Check the peripheral circuits at pins 14, 15 and 20 on IC1, and CNS1A/B.
Yes
A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 20 on IC1.
"Initialization" is not possible.
Data cannot be read. Check the VCO-PLL system.

Figure 7-3-1 2-3 Spin system check.
Press the OPEN/CLOSE switch without inserting a disc, and then try starting the play operation.
1. The turntable rotates a little ? (Waveform drawing Figure 7-3-2) No 2. The turntable doesn't rotate.
The spin driver circuit is OK. Yes
Check around pin 22 on IC1, pins 15 and 16 on IC2, and CNS3A/B.
