very good quality readable manual,printed off very well.
;
The manual was very accurate for the part that I was changing, I was able to order the correct part and had no issues with the replacement procedure. However, I was expecting to have more detailed repairs for the lower drive unit.
 ;
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.
G) SET UP level adjustment circuit The circuit consisting of Q307 and RV302, or Q323 and RV313 sets SET UP level. SET UP level can be adjusted to specified level adjusting by RV302 or RV313. H) White clip level adjustment circuit The circuit consisting Q308, Q328 and RV309, or Q324, Q329 and RV314 sets white clip level. White clip level can be adjusted to specified level adjusting by RV309 or RV314. I) SYNC MIX circuit SYNC signal supplied from pin 14 of CN301 is adjusted of its level adjusting by RV310, mixing it to VIDEO output signal 1 passed through Q310 buffer amp. The other side, VIDEO output signal 1 passed through Q308 buffer amp, is adjusted to specified level adjusting by RV317, and sent it to pin 2 of CN302 then becomes output from the PR-257 board. SYNC signal is adjusted of its level adjusting by RV310, mixing it to VIDEO output 2 signal too passed through Q326 buffer amp. VIDEO output signal 2 passed through Q308 buffer amp, is adjusted to specified level adjusting by RV315, and sent it to pin 4 of CN302 then becomes output from the PR-257 board.
