B7-080902 Linear Power Supply PCB

This image features a Printed Circuit Board (PCB) identified by the model number B7-080902. This specific board is a linear power supply module typically used in audio equipment, such as active speakers or amplifiers. It utilizes components like TIP41C/TIP42C transistors, electrolytic capacitors, and bridge rectifiers to convert AC voltage (labeled AC15V) into stable DC power for electronic circuits.

As a generic electronic component part of the global electronics supply chain, it does not carry a consumer brand name like Sony or Samsung. Instead, it is manufactured as an Original Equipment Manufacturer (OEM) or white-label part by various electronic assembly plants. These units are predominantly produced in industrial hubs in China and are distributed globally for repair services or DIY electronics projects. Ownership of the design typically resides with the generic manufacturing entity that produces it for the open market.
