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
YH Adjustment (VR2 for vertical dynamic convergence) 1. Apply a crosshatch pattern. 2. Adjust contrast and brightness customer controls to obtain a correct picture. 3. With a driver Adjust VR2 (located in deflection yoke board Fig. 19) to obtain a proper corvergence at left and right side of the screen. (see Fig. 14)
Permalloy convergence corrector strip (part No. 0FMK014ZZ)
This strip is used in some sets to match the yoke and CRT for optimum convergence. If the yoke or CRT is replaced, the strip may not be required. First converge the set without the strip and observe the corners. If correction is needed: 1. Place strip between CRT and yoke, in quadrant needing correction. Slowly move it around for desired results. 2. Press adhesive tightly to the CRT and secure with tape.
DAF adjustment
Preparation: 1. Apply a crosshatch pattern. 2. Set user controls, bright to center and picture to max. 3. Connect a frequency counter to TPD10. Procedure: 1. Connect channel one of the oscilloscope with 100x1 probe to TPP33 (pin-1 T1551). 2. Connect channel two of the oscilloscope with 10x1 probe to CRT HEATER (L-Board). 3. Adjust �HDAFP� so both waves are in the same position. 4. Adjust �HDAFW� so TPP33 is 1.5 ± 0.5kVpp.

XV Adjustment (precise adjustment)
1. Apply a crosshatch pattern. 2. Adjust contrast and brightness customer controls to obtain a correct picture. 3. With a driver adjust the coil located in deflection yoke board to obtain a proper convergence horizontally.
