Thanks!

Re: Thermistor Selection Help Needed

A couple of years ago one could buy one of these (Dell N650P-00) for under $100. Now I can't find one under $200, and that's for a refurbished one. :o( Any suggestions?

Re: Thermistor Selection Help Needed

Thank you Pete. This is the second Dell Precision 670 power supply that has failed the exact same way. Manufacturing default? Another ham radio friend of mine recommended I not bother fixing it and to buy a complete replacement.

BTW, I used to live in Santa Cruz and am a SJSU alumnus. :o)

I'm rebuilding my Dell computer's power supply that failed the other day. :o(

Re: New Members - please post your introductions here

Hello,
I'm a retired product design engineer from Silicon Valley who has been working with computers ever since the introduction of CAD. (Still miss the old drafting board, though). Now homesteading on the coast of Oregon and sharpening my ham radio skills. As is always the case, tinkering and repairing electronics, mechanical devices and motors. You name it, I'll tackle it. This looks like a very useful forum. Glad I found it! :o)
