Randy, I show BU806 (PN: 610532-3) for Q400. Sorry, that's all I have. (Not sure what you mean by your last paragraph, what PN: 8721 is). -Clint God Bless Us All Clint Hamilton, Owner http://OrpheusComputing.com sales@xxxxxxxxxxxxxxxxxxxx Fax: 209-882-9602 TechAssist Administration http://tech-assist.org techassist@xxxxxxxxxxxxx (PLEASE include previous correspondence if replying to this email!!) ----- Original Message ----- From: "Randy Prothero" <Randy@xxxxxxxxxxxxxxxxxxxxxx> To: <techassist@xxxxxxxxxxxxx> Sent: Saturday, November 10, 2001 12:39 PM Subject: [TechAssist] Part number for Switch Mode Transistor on C9 chassis Can someone please share the part number (phillips, i assume) for the switch mode transistor (Q400) on a C9 chassis? Also, is it possible to grab the part numbers (or values for diodes) for D400-D404,Q402,Q403? I see the actual part is a Motorola part #8721 if that helps. I am having difficulty crossing it with the actual "replacement part". Thanks Randy ***************************************** Help make your TechAssist online repair tips database better!
