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
2-4. White Balance Adjustment on Servicing
2-4-1. White Balance Adjustment
Input the 10 STEP signal to INPUT-A, and observe the chromaticity of each luminance. When varying the chromaticity of each luminance, perform the following adjustments. 1) MID Mode of INPUT-A 1. 2. 3. 4. Input the 100 IRE FLAT FIELD signal to INPUT-A. Measure the chromaticity (x, y). Input the 80 IRE FLAT FIELD signal to INPUT-A. Adjust the chromaticity (x, y) to the values measured in step 2, by the GAIN R and B of W/B MID mode. 5. Set the INPUT signal to the 30 IRE FLAT FIELD signal. 6. Adjust the chromaticity (x, y) to the values measured in step 2, by the BIAS R and B. 7. Repeat above steps 3 to 6 until the chromaticity become the following values. x ± 0.002, y ± 0.004 (The x and y are the values measured in step 2.) 2) HIGH Mode of INPUT-A 1. Input the 80 IRE FLAT FIELD signal to INPUT-A. 2. Set the GAIN G to MID mode value at �_20� with the HIGH mode of the W/B. 3. Set the BIAS R, G and B that are equal to MID mode values. (Set the BIAS R, G and B to the same as MID mode values.) 4. Input the 30 IRE signal to INPUT-A. 5. Adjust the chromaticity (x at 0.284, y at 0.298) values by the BIAS R and B of W/B HIGH mode. 6. Input the 80 IRE signal to INPUT-A. 7. Adjust the chromaticity (x at 0.284, y at 0.298) values by the GAIN R and B. 8. Repeat above steps 4. to 7. until the chromaticity become the following values. x: 0.284± 0.002, y: 0.298± 0.004
3) LOW Mode of INPUT-A 1. Input the 80 IRE FLAT FIELD signal to INPUT-A. 2. Set the GAIN R that is equal to MID mode value. (Set the GAIN R to the same as MID mode value.) 3. Set the BIAS R, G and B that are equal to MID mode value. (Set the BIAS R, G and B to the same as MID mode value). 4. Input the 30 IRE signal to INPUT-A. 5. Adjust the chromaticity (x at 0.313, y at 0.329) values by the BIAS R and B of W/B LOW mode. 6. Input the 80 IRE signal to INPUT-A. 7. Adjust the chromaticity (x at 0.313, y at 0.329) values by the GAIN G and B. 8. Repeat above steps 4 to 7 until the chromaticity become the following values. x: 0.313± 0.002, y: 0.329± 0.004 4) MID/HIGH/LOW Mode of VIDEO 1. Input the VIDEO signal of NTSC or PAL. 2. Set the BIAS R, G and B and GAIN R, G and B of MID, HIGH and LOW mode of W/B that are equal to the values of corresponding items in INPUT-A. (Altogether 18 items) 3. Set the GAIN G only of MID mode of W/B value at �_16� in INPUT-A.
2-5. Tilt Adjustment
n Do not put the unit upward and downward in the vertical direction for more than ten seconds. 1. 2. 3. 4. 5. 6. 7. 8. Set the Factory mode to �Device Adjust/OTHER�. Set the adjuster in contracted position. Then, enter the X TILT value to C0. Set the unit upward in vertically. Then, enter the X TILT value to C1. Set the unit downward in vertically. Then, enter the X TILT value to C2. Save the each values of C0, C1 and C2 described in step3, 5 and 7.
