If you have noise, intermittent output or complete loss of output of one or more channels, a bad output relay is a likely cause.  These relays are drop-in replacements for the original parts (they are marked with the manufacturer's part number, not Denon DH2TU or DH24D2).  The relays have high quality silver contacts for low noise and current handling specs that exceed the original parts.  Each receiver uses two or more relaysThe parts are brand new and will be shipped in protective packaging.  Relays are UL Recognized.   The listing is for the relays only, not the complete receiver.

If you have noise, intermittent output or complete loss of output of one or more channels through the loudspeakers, try listening to the unit through headphones.  If the sound is clear through the headphones, you know it's likely the relay(s) or the output stage.

The parts can be replaced by a person with limited soldering skills.  A soldering iron, solder wick and solder are needed to replace the parts.  Use standard safety precautions (wear safety glasses, unplug the unit before soldering, etc) when working on your gear.  When you're done soldering, always wash your hands because solder often contains lead.  Please note that replacing the relays will fix the receiver only if the relay was the problem to start with!
