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.

1 Remove six black screws (M3 x 10). 2 Remove six white screws (M3 x 12). A Screw holes in the PCB are printed with
numbers 1 to 12. Remove screws in numerical order. Re-assembly takes the reverse order of disassembly. Caution) The Amp Unit is adhered on the Heat Sink with silicon grease. This means forcibly removing the Amp Unit from the Heat Sink may break the PCB.

Remove all of the twelve screws. Then, remove the two black screws (M3 x 5). Tighten screws whose length is M3 x 8 or more into the two screw holes so as to raise the Amp Unit above the Heat Sink. Then, remove the Amp Unit. (Since screw threads differ, 1 and 2 screws cannot be used.)

Caution when re-assembling the Amp Unit and the Heat Sink
Be aware that the RCA Terminal may break unless the Amp Unit and the Heat Sink are assem-bled following the correct procedures given below. 1) Secure the RCA-side Panel on the Heat Sink with screws. (Fig. 2) 2) Place the Amp Unit on the Heat Sink aligning with two studs. (Fig. 4) 3) Move the Amp Unit until the RCA Holder on the Amp Unit comes in contact with the inside of the Panel. (Fig. 4) Caution in steps 2) and 3) When you place the Amp Unit on the Heat Sink, you will find no positioning marks to determine the direction of two panels. To position them correctly, the Amp Unit needs to be moved to the place where it comes in contact with the RCA-side panel. If you do not position them, an excessive force can be applied to the RCA Terminal. This may result in breakage. 4) Secure the RCA-side Panel and the RCA Holder with screws. (Fig. 2) 5) Secure the Amp Unit on the Heat Sink with screws. (Fig. 3) 6) Secure the Panel for the Power Terminal side in place with screws. (Fig. 2)
