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.

High Voltage Regulation Adjustment
Digital Multi-Meter(DMM)
4) HS (Horizontal Shift) Adjust so that the horizontal center line of a digital circle pattern is in accord with geometric horizontal center of the CPT. 5) EW (East-west Width) Adjust until the outermost left and right vertical line of the screen is accord with the edge of the frame. 6) EP (East-west Parabolar) Adjust so that middle portion of the outermost left and right vertical line looks like parallel with vertical lines of the CPT. 7) ET(East-west Trapezium) Adjust to make the length of top horizontal line same with it of the bottom horizontal line. 8) A-ANG(AFC Angle) 9) A-BOW(AFC BOW) 10) U-C(Upper Cotner Pincushion) 11) L-C(Lower Cotner Pincushion) 12) U-VL(Upper Vertical Linearity) 13) L-VL(Lower Vertical Linearity) 14) VL (Vertical Linearity) Adjust so that the boundary line between upper and lower half is in accord with geometric horizontal center of the CPT. 15) SC (Vertical �S� Correction) Adjust so that all distance between each horizontal lines are to be the same. 16) V-ASP(Vertical Aspect Ratio) Adjust the vertical aspect ratio.
1. Test Equipment 2. Preliminary steps
1) Switch picture mode to STANDARD in no signal input.
3. Adjustment
1) Connect �+� terminal(Red) of DMM to the Anode of D432 and �-� terminal(Black) to the Heat Sink of Q406. 2) Adjust VR401 so that the D432 terminal voltage is 21.3!0.1V.

CUT-OFF Adjustment
1) Press the �SVC� button and then press the � � button on the remote controller for adjustment to display horizontal
line.(Even though you enter into the SVC mode, the horizontal line might not be seen according to the position of Screen Volume.) 2) Adjust Screen Volume (R/G/B) in Focus Pack until brightness of red/blue/green horizontal line is about not to be seen.(At this moment, brightness of red, blue or green horizontal line should be equal to one another.) 3) Exit the adjustment mode by pressing the � � button.

Deflection Adjustment
1) Adjust differently based on input signal such as NTSC or PAL. 2) NTSC adjustment should be done in STANDARD mode of picture after receving 13CH signal,and PAL adjustment should be done in STANDARD mode of picture after receving EU05 CH. 3) Reset the data in convergence adjustment mode,quit the mode. Convergence Mode : SVC, M Data reset : 5 , OK Adjustment mode out :
M
1. Preliminary steps
17) Store the adjusted data in EEPROM by pressing the �OK� button before exiting adjustment mode. 18) Restore the convergence correction data by pressing the �TV/AV� button before exiting adjustment mode
2. PAL Mode Deflection Adjustment
1) At SVC mode,press the YELLOW key get into the deflection adjustment mode. 2) VS (Vertical Shift) Adjust until geometric vertical certer line of the screen is accord with the vertical center line of the screen JIG at EU 05 CH by pressing the VOLUME F ,G button. 3) VA (Vertical Amplitude) Adjust until fifth vertical line from upper and lower center of the screen is accord with the edge of the frame.
3. NTSC Mode Deflection Adjustment
1) Adjust vertical size (VA Adjustment) until fourth vertical bar from upper and lower center screen is accord with the edge of the frame. 2) Adjust horizontal size (EW Adjustment) until third bar to indicate horizontal size of circle is accord with the edge of the frame. 3) Do other adjustments the same as in PAL mode.
