Bose Acoustimass 300/700. Dead/No Power Fix. 1x B2100-13F 100v/2A Diode. Position J401 This is a sale of the most common component to fail on these sub woofers, not a complete unit. While this is the most common component to fail there maybe other reasons as well. As this is an SMD device a reasonable level of soldering skill will be required.
