Im fixing my fried Crossfire amp and need to replace 4 mosfets but I cannot locate them to be sold anywhere in town or online, i tried parts express with nothing. The part # is IRFB31N20D, if anyone can help me locate that and a 0.04 ohm power resistor made by HMR, part # oro4(ohm)F.

Im having no luck finding this stuff.

Thanks

Thanks, I ended up finding the fets at Newark, but I cannot match up my resistor that is made by a manufacture code HMR, do you know what company that is? I searched NEMA with no luck.

HMR is a South Korean company. They make metal oxide film resisters and larger wire wound resisters. I bet your's is a high precision (0.5%) MOS resister and I suggest you need to match size and type but not necessarily brand. Here's their contact info but I doubt it'll do you much good. Maybe you can email them from their web site:

HMR Co Ltd

159-43, Sosabon-Dong

Sosa-Gu

Bucheon-City

Gyeonggi-do

South Korea

Thanks so much for your help! Looks like I can repair a whole stage on this amp for $20 doing it myself vs. paying crossfire $250 electrical parts dealers? -- posted image.
