Denon 943639106000s Smps Pcb Assembly AVR-S970H

Product Description

The DENON 943639106000s is a switched-mode power supply (SMPS) printed circuit board assembly designed as a direct OEM replacement for the AVR-S970H E3 series AV receiver. This board serves as the internal power conversion unit, regulating and distributing DC voltage to the receiver's core electronics. It is a factory-sourced assembly intended for installation by qualified electronics technicians or experienced AV service professionals performing component-level repairs on Denon and Marantz consumer AV equipment.

This SMPS PCB assembly is intended for use in the Denon AVR-S970H E3 AV receiver. It is a board-level replacement part suited to depot repair and field service scenarios where the original power supply board has failed due to component-level faults such as blown capacitors, failed rectifiers, or other power-stage failures. Technicians performing receiver service will find this assembly an exact-fit substitute for the original installed unit.

Key Features

• OEM SMPS board assembly sourced directly for the AVR-S970H E3 platform
• Factory-configured power conversion and voltage regulation circuitry
• Drop-in replacement for failed or damaged original power supply boards
• Supports component-level AV receiver repair without chassis modification

Compatibility

Designed as a direct OEM replacement for the Denon AVR-S970H E3 AV receiver power supply board. No other compatibility is stated in the available product data.

Installation Notes

Installation should be performed by a qualified electronics technician with experience in AV receiver service. Disconnect the unit from mains power and allow sufficient time for internal capacitors to discharge before handling any internal PCB assemblies. Follow all applicable electrostatic discharge (ESD) precautions when handling the board. Verify all wiring harness connectors are fully seated and secured before restoring power.
