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.

Perfect like it was descriped, Perfect like it was descriped

INSTALLATION AND SERVICE INSTRUCTIONS
Note: (1) When performing any adjustments to resistor controls and transformers use non-metallic screwdrivers or TV alignment tools. (2) Before performing adjustments, the TV set must be on at least 15 minutes.
CIRCUIT PROTECTION
The receiver is protected by a 5.0A fuse (F701), mounted on PWB-A, wired into one side of the AC line input.
HIGH VOLTAGE CHECK
High voltage is not adjustable but must be checked to verify that the receiver is operating within safe and efficient design limitations as specified checks should be as follows: 1. Connect an accurate high voltage meter between ground and anode of picture tube. 2. Operate receiver for at least 15 minutes at 120V AC line voltage, with a strong air signal or a properly tuned in test signal. 3. Enter the service mode and select the service adjustment "S19" and Bus data "01" (Y-mute on). 4. The voltage should be approximately 32.8kV(32RS50, 32R-S400)/33.4kV(36R-S50, 36R-S400) (at zero beam). If a correct reading cannot be obtained, check circuitry for malfunctioning components. After the voltage test, make Y-mute off to the normal mode.
X-RADIATION PROTECTOR CIRCUIT TEST
After service has been performed on the horizontal deflection system, high voltage system, B+ system, test the X-Radiation protection circuit to ascertain proper operation as follows: 1. Apply 120V AC using a variac transformer for accurate input voltage. 2. Allow for warm up and adjust all customer controls for normal picture and sound. 3. Receive a good local channel. 4. Connect a digital voltmeter to TP653 and make sure that the voltmeter reads 13.8 ±0.7V (32R-S50, 32RS400)/13.2 ± 0.7V(36R-S50, 36R-S400). 5. Apply external 17.0V DC (32R-S50, 32R-S400)/ 16.2V DC (36R-S50, 36R-S400) at TP653 by using an external DC supply, TV must be shut off. 6. To reset the protector, unplug the AC cord and plug the AC cord power on. Now make sure that normal picture appears on the screen. 7. If the operation of the horizontal oscillator does not stop in step 5, the circuit must be repaired before the set is returned to the customer.
