Lite-On PA-6601-1 - seeking help to identify blown transistor Q307A
Hi,
trying to revive a dead power supply Lite-On 600W TESLAconverter PA-6601-1 manufactured in 2003 and originally used in a PowerMac G5. Transistor Q307A underneath a heat shield was blown - it was labelled A2700 H403. How do I go about finding a replacement transistor? Thanks & cheerio, Harry. |

uPA2700 N-CH MOSFET.
Trace out the connections to see if it makes senses.
