as above, i've bought replacement mosfets to repair alpine v12 amps 5-6 years ago for $30 but newer amps may not be as easilly worked on like the older ones...
what's wrong with ur's?

Hmm, More often than not, When the Fet's pop, It usually takes the rest of the amp with it.
Well enough to not be worth fixing anyway.
You could spend a week replacing bad component's, And still have a non working amp.


I'd open it up, See how many fet's are damaged, And go from there.
Have a poke around with a multimeter and try pinpoint other damaged component's.

I have worked on a few amp's, Sometime's you can get lucky and just replace the fet's, And other's the amp is toast as far as cost goes.

When you replace the mosfet's, It's a good idea to replace them all from the same batch.
So, If you blew 2 power fet's out of 6, Then you would want to replace all 6 power fet's, Otherwise they may blow again due to slightly diffrent tolerances.
Same goes for the output mosfet's.

Im just assuming here, It may be a bad cap, wich can be easily replaced.
Just need to open it up and have a look.

Get you're self a schematic.

like over half of the transistors are gone looks like they caught on fire

gut it, take the alloy in for scrap and put the proceeds towards a new amp
