Hi, I'm new to this stuff. I have a Zapco 1000w amp and burt some mosfets and I want to fix it myself, with that being said I need to know something.

The Mosfet has the numbers
IRFZ46N
I diode sym R 026k
5K 9H
I've looked everywhere I could and I can't find anything with all the numbers, Do the other numbers other than the IRFZ46N?
also the stamp in the plastic says K8K.

Thanks

Please post clearly focused pictures of the parts.

Mouser has the MOSFET:

Simply replacing damaged parts isn't guaranteed to fix the problem. When power transistors burn out, there's usually something that causes them to do that.

 

IRFZ46N is an N channel MOSFET. This is the data sheet. The IRFZ46N is the actual part number. Other numbers could be for example a date code. Pretty common MOSFET too. You can buy from a collection of distributors depending on location.

Edit to say never mind as dl324 was faster than I was.

From looking at the amp, looks like the 12v in solder had melted enough to touch the chassis of the amp. Thanks for all your help : )
