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.

Very good detail, all pages clear, exactly what I needed
VCC3, VCC5 voltage check PCB-LA � Voltage supply CP151 = 5.0 ± 0.05 V. (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Apply 5.0 ± 0.05 V to CP150. (2) Make sure VCC3 (CP160) is 3.3 ± 0.1 V and VCC5 (CP152) is 5.0 ± 0.15 V.
VCC2 adjustment and VCC7, VCC8, VEE2 voltage check � Voltage supply VCL0(CP101)=5.0±0.05V. (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Apply 5.0 V ± 0.05 V to VCL0 and adjust VR100 so that VCC2 will be 5.0 ± 0.02 V. Notes: � VCC7 = 7.3 ~ 8.3 [V], VCC8 = 12.0 ~ 14.0 [V] � VEE2 = �12.3 ~ �16.7 [V] In addition, disconnect the power and make sure all output voltages are 0 V.
VCO free run frequency adjustment � Voltage supply VCC2=5 V ± 0.05 (V) (CP181). VCC8 = 13.5 ± 0.05 (V) (CP180). VEE2 = �15.0 ± 0.05 (V) (CP182). Connect CP705 (CSY) and CP700 (GNP). (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Monitoring CP710 (HDB) with a frequency counter, adjust VR720 so that the frequency will be 15.734 ± 0.1 [KHz]. Notes: � Disconnect CP705 and CP700, then connect PCB-LA and make sure CP705 (CSY) and CP710 (HDB) are synchronized. � Keep room temperature at 20 ± 10°C. QV-770
