The Grundig Satellit 750 (also sold as the Tecsun S-2000) is a legendary flagship shortwave receiver favored by DXing enthusiasts worldwide. Combining a classic desktop aesthetic with advanced dual-conversion circuitry, this radio offers exceptional sensitivity across AM, FM, Shortwave, Longwave, and Aircraft bands. However, like any sophisticated piece of RF (Radio Frequency) hardware, maintaining its peak performance over time requires technical intervention.
Check the audio output IC (typically a TDA series or clone). Verify supply voltage at its VCC pin. Touch the input pin with a metallic tool; if a loud hum is heard, the IC is functional, and the issue lies earlier in the audio pre-amp stage.

If you are currently trying to diagnose a specific issue with your radio, I can help you narrow down the root cause. Could you tell me:
Clean the encoder with high-purity electronic contact cleaner, or replace the rotary encoder module as specified in the parts list. Backlight Failure or Flickering LCD Check the audio output IC (typically a TDA series or clone)
Tune to a known accurate AM broadcast station. Switch to SSB mode. Set the BFO knob to exact dead-center. Adjust the BFO reference trimmer capacitor on the Main PCB until the station whistle drops in pitch to zero Hz (complete clarity without a underlying tone). 6. Comprehensive Troubleshooting Guide
