Ed, Everyone of these I have seen, the REG gets mounted to a heatsink...writing goes out.

I have had non-OEM's come in 3 in the back and 4 in the front (STR not STK) And the tendency is to put them in the way the pins are pre-formed, which means it's actually in backwards. Have found this in the Toshiba set only. -Ed- Ed Gaidies Tel-Tek Electronics Ontario-Canada teltek3@xxxxxxxxxxxx ----- Original Message ----- From: "Intrepid Video Support" <support@xxxxxxxxxxxxxxxxxx> To: <techassist@xxxxxxxxxxxxx> Sent: Friday, August 22, 2003 5:42 PM Subject: [TechAssist] Re: Toshiba Model cx2950c chassis 8820 Dead > Ed, > Not sure how you can place one of these in backwards. > The thing with the legs formed the wrong way, merely means you got a wrong OEM part. > Emerson, I think, is the one who has their regulators proprietary to them, even though they have the same > STK number. > > > Jeff Dougherty > Intrepid Video TV/VCR > 263 S Front St > Steelton PA 17113 > fax...717-564-4952 > www.intrepid-video.com www.tech-repair.net > > ----- Original Message ----- > From: "Teltek3" <teltek3@xxxxxxxxxxxx> > To: <techassist@xxxxxxxxxxxxx> > Sent: Friday, August 22, 2003 8:00 AM > Subject: [TechAssist] Re: Toshiba Model cx2950c chassis 8820 Dead > > > I think I mentioned this before.
