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.

1. Clock Frequency Check Settings : � Test point : TP2 (CLK) Method : Set to MW 1602kHz and check that the test point is 2052kHz ± 45Hz. 2. MW VT Check Settings : � Test point : TP1 (VT) Method : Set to MW 1602kHz and check that the test point is less than 8.0V. Then set to MW 531kHz and check that the test point is more than 0.6V. 3. MW Tracking Adjustment Settings : � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : L981 (1/3) Method : Set to MW 999kHz and adjust L981 (1/3) so that the test point becomes maximum. 4. LW VT Adjustment Settings : � Test point : TP1 (VT) � Adjustment location : L942 Method : Set to LW 144kHz and adjust L942 so that the test point becomes 1.3V ± 0.05V. Then set to LW 290kHz and check that the test point is less than 8.0V. 5. LW Tracking Adjustment Settings : � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : L941 ........................... 144kHz TC942 ......................... 290kHz Method : Set up TC942 to center before adjustment. The level at 144kHz is adjusted to MAX by L941. Then the level at 290kHz is adjusted to MAX by TC942. 6. AM IF Adjustment Settings : � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : L772 ........................... 450kHz 7. FM VT Check Settings : � Test point : TP1 (VT) Method : Set to FM 108.0MHz and check that the test point is less than 8.0V. Then set to FM 87.5MHz and check that the test point is more than 0.5V. 8. FM Tracking Check Settings : � Test point : TP8 (Lch), TP9 (Rch) Method : Set to FM 98.0MHz and check that the test point is less than 13dBµV. 9. DC Balance / Mono Distortion Adjustment Settings : � Test point : TP3, TP4 (DC balance) � Adjustment location : L771 � Input level : 60dBµV Method : Set to FM 98.0MHz and adjust L771 so that the voltage between TP3 and TP4 is 0V ± 0.04V. Then check the distortion is less than 1.3%. 10. Output Level Check <MW> Settings : � Test point : TP8 (Lch), TP9 (Rch) � Input level : 74dBµV Method : Set to MW 999kHz and check that the test point is 50mV ± 3dB. <FM> Settings : � Test point : TP8 (Lch), TP9 (Rch) � Input level : 60dBµV Method : Set to FM 98.0MHz and check that the test point is 220mV ± 3dB. 11. FM Separation Check Settings : � Test point : TP8 (Lch), TP9 (Rch) � Input level : 60dBµV Method : Set to FM 98.0MHz and check that the test point is more than 12dB.
