he did have two hd 15ks blow out on him so he has a good personal reason but he's also seen others use the amp with great success but personal experiences overwrite all that.
Ready for the twist at the end? No he didnt.
I do not represent ourselves as repair tech so can only relay what our repair center has shared with us and then what we actually have in our hands at the time we received it from the repair center.
1 did blow, the other went into protect. This is user's own words.
Repair center-
Practically ALL mosfets blew in the power supply section. The only way to replicate this is to go full on clipping (which full bridge amps do not like) or voltage drop way too low.
We know the amplifier worked on low volume but as soon as it was turned up (per user's words) it popped.
Now, we do not play who did it because we warranty the amplifier for free even if you wired it to 0.1ohm for daily which no other manufacture will do.
But here is the twist that none of you know about-
The other amplifier was reported to go in protect.
To this very day, when they were sent back to us, then sent to repair center, the repair center has done NOTHING to the "protect amp" and it has played flawlessly the entire time. It was returned to us once the other one was repaired and still no problems with the protect amp.
That clearly shows us, along with the blown amp, that the user has/had something wrong in their install. Amp don't choose to go into protect because it has feelings. Something tripped it's circuitry and blamed it on the manufacturer.
Many of us in this conversation ever here the majority of people who badger brazilian amplifiers roll their eyes when people say failures are mostly due to user error?
Well, here is a clear cut case.
Nobody physically blames the person personally as if they aren't worthy of the equipment but rather at least try and educate the masses that nobody is perfect and can make human error in their install.. or simply something out of our control happens and messes up something.
We are National Tech Advisor for Taramps for a reason but in this instance, user decided to go around warranty service, cheated themselves out of equipment by assuming it was faulty and got a refund.. when our repair center educated us that one was not defective and the other has no problem at all.
I know some will ask.. since then, i'm sure the user has installed new equipment that works so explain that?
Simple. Different buildhouses, not brands but buildhouses make their own designs, own schematics, etc.
There is no 1 protection circuit everyone uses for example. It's quite simple to say our protection circuit tripped on something that the replacement product must not be designed to do. Beyond that, everything else is speculation.
Speaking of protection, that new MD8000 amplifier is going to be a beast..
Rated at 1%THD instead of 10%.
Rated at 12.6v instead of 14.4v
Rated at 60hz instead of 100Hz or even 1000Hz on some brazilian brands.
And still half the length of a korean 8-10k.
Oh, and 7way protection (including dual short circuit protection on the output).
