Amp fixing question

[MitchZ 10+ year member]

I bought my amp to a local repair shop, the guy tested all the transistors and told me which ones I need to order. (because his supplier doesn't carry these certain transistors)

I need these:

fb31n20d x 6

irf3205 x 4

I've been looking around and seeing lots of IRF3205PBF and IRFB31N20DPBF or other letter combinations after the actual one I need.

Will any of them work or do I need the exact part number?

I haven't looked very long, I just came across this.

irf3205 is obsolete. nte2991 is a replacement according to mouser.com theres a cheaper STMicro chip available too just search for "irf3205".

quick search didn't pull up anything for the other one. what kind of amp is it?

It says the correct part number and the correct part number with PBF on the end.

Will it be okay?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Yes it "should" work. Don't know if they ship to canada but

"http://www.newark.com/57J2554/semiconductors-prototyping/product.us0?sku=INTERNATIONAL-RECTIFIER-IRFB31N20DPBF"

is cheaper. I believe the PBF on the end means lead free so that it is RoHS compliant.

on a side note. I'm not sure how much you are paying for this repair but unless it is really cheap. I would take my business elsewhere. IMO finding and ordering parts should NOT be the customers responsibility.

Yeah, hes just charging me 60$ for labour. (To test everything and solder transistors)

I don't think its that bad...

I was quoted 300$ somewhere else.

So this way it will only be 100$ to 120$

 

[Hostile89 10+ year member]

60 bucks isn't bad.

Ok so I ordered the transistors.

Turns out to be 62$ shipped for all of them.

Thanks to everyone who helped in this thread. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
