Keepin it Simple
The MOSFETs on my MD22 are fried out and I can't find replacements. Can anyone help out? Also, what goes into making it an MD23?
To be honest, I don't think you have the knowledge to repair an amp properly. You can try, and you may succeed, but don't be surprised if you don't. If it's an amp you don't really care about, go for it, if you really need to get it working again you should send it to a repair shop. When components burn up in a circuit it doesn't generally just fail and turn off, they end up sending enormous amounts of current to other components that may fail or get damaged without showing any signs (i.e. no charring or soot). So there's a very good possibility that you'll burn up all your newly soldered in fets the second you power that amp back up because something else in the circuit is damaged.They are labeled as SFP50N06 but I can't find anywhere to purchase them. And I know you can mod this amp into an MD23...figured while I have it apart, and if it's not too much more, I might try that too.
I'll be the first to admit, I know little to nothing about how this all works...electronically speaking. But I can replace and solder in new stuff with no issues. So yeah...not even sure what a gate resistor is, lol.
Save your money and just take it to someone now. Not only will you waste money on parts, you run the risk of damaging the amplifier further yourself.Thanks for the concern and I am well aware of all this. I honestly don't expect it to work. I called USAmps/REaudio and they said anywhere between $100-$200 to fix it. So I figured I'd take a whack at it. If it doesn't work I'll try to find someone local.
