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.

3. Why to adjust PG delay : To compensate mechanical tolerance by adjustment.
4. Concept of automatic adjustment To adjust 6.5H means to set the time from SW.P to V.Sync at 6.5H. We can do that by compensating the undesired time as long as we can check the time between the two. The micom check the gap between SW.P and V.Sync by resolution of 2 § �(1H à 64 usec ) . After comparing the checked time with actual 6.5H, the difference is compensated and then SW.P is output. With this kind of method, we can get the effect same as manual adjustment in the past. result is saved in an EEPROM so as to keep the data in spite of RESET mode. And also, all the
5. Process In Automatic adjustment mode, The micom makes progress to fix PG delay to 9.14 degree maximum range as controllable as, to get average time from to check SW.P and V.SYNC�s time be read from Tape as 4 times, to compensate the time equivalent to 6.5H. Under the time compensated condition, The micom makes recheck SW.P and V.SYNC�s time, if the result is in the range 6.5H ¡ ¾.0H, then the DATA will be saved to EEPROM, or not repeat this 1 process with adjusted state
