ATTN db-r (reguarding mosfets on audiopipe ap30001d) I have the numbers

so whats the performance difference of the upgrades and price please. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

LOL. After I get my hands on one and experiment then I can tell you.

Hey, with the price I got them at, I can afford to beef the shit outta them if needed. lol. I know and have experience with your work so I'll only trust you.

Yeah, I think these are prime candidates for "beefing" since they are under 200V and use all N-Channel outputs there is a wide array of mosfets that can swap in place of the IRF640N's and also, the power supply depending on how much current the transformers will take, and the rectifiers (which can be upgraded too), should be able to be upgraded as well. Just depends on the transformers, those are gonig to be the limiting factor.

By beefing up are you referring to running at lower ohm loads, or more power. or both?

 

[dB-r 10+ year member]

Both.

Make sure you let us know if this becomes feasible. I have 3 3k's that I would be interested in doing this too......

LOL, if I do end up doing it, it's not going to be cheap, and If there is any custom circuit mods for the protect circuits or anything it will include surface mount soldering which is not something that everyone can do. Especially people with big *** fingers.... so you would have to send it here to be done basically, and like I said, not going to be cheap. It's more to satisfy my curiousity than anything else... The excess current might even burn the PCB in half....

IN HALF? Sweet. Take vids.

sounds like should have just spent a little more money and got a better built amp..

 

[slim2fattycake 10+ year member]

lol.

I have no problems with mine. If I can get more performance out of them and still stay under what other amps in the same power range cost then I'm fine. They do exactly what I need them to do. I would like them to be ran down to 1 ohm bridged daily. I will try them out on burps soon.

Agreed.

The point is an experiment.

So I can have some evil scheming for the weekend,

What are the candidates for FET swapping, in place of the IRF640N's?

I'd gladly help with the experiment (*chants of "Sacrifice!" in the background*), and don't have "sausage fingers" for surface-mount parts. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

running my 30001 @ 1ohm daily for a week no problems. have burped to show off for customers a few times too....
