 ;
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.

6.2.6 Audio Module Tuning Instructions
6.2.6.1 TX-Audio
- feed a 1 kHz sine signal of 4.0Vrms to connector pin 5 (via local box, GENconnector) - enter 0 # and 21 # and 215 # (read phone level) - change the signal frequency to 2 kHz at 4.0Vrms - if the RF module is present, enter also 31 # - if the RF module is not present, connect an oscilloscope to the X-RF connector pin 17. - enter 201 # 4 and use the +/- keys to adjust the oscilloscope to show 2075...2125mVpp and press the F key. If the RF module is present, set the deviation to 4,5...4,7 kHz and press the F key.
- change the input sine signal to 1 kHz at 400mVrms. - press 1 and use the +/- keys to adjust the oscilloscope to show 1510...1530mVpp and press the F key. If the RF module is present, set the deviation to 2,95...3,05 kHz and press the F key. - press the C key.
Check the deviation limiter as follows and tune if necessary: - change the signal level to 4.0Vrms keeping the frequency at 1kHz. If the deviation does not exceed 3.7 kHz, enter 217 # and raise the tuning value with the + key one step at a time until the deviation rises above the limit, and press the F key. If the deviation is already above 3.7 kHz, press the F key. - change the frequency to 650 Hz. If the deviation exceeds 4.7 kHz, use the + key to increase the tuning value one step at a time until the deviation drops below the limit, and press the F key. If the deviation is already below 4.7 kHz, press the F key.
