Massive 1500W Amplifier
 
Hello
I am newbie, I know little electronics and Little Audio Amplifier Diagrams,I want to build A Masssive 1500W Amplifier

Things I will need

Massive 1500W Transformer
High Current Power Transistors
Large Eletrolytic Capacitors
Power Resistors

I also will need your help!

So let's build this monster

Not a recommended project for a newbie.

You won't be able to build one for these prices, you won't have a warranty, etc.

If you are NEW to electronics, start with a 1W amplifier first, and take your learning from that to build bigger over time.

It seems like a lot of new folks want to fantasize about building a HUGE amp, but the reality is that you have to start small and learn first.

Yikes , what you said does not compute !!!:D :D

First of all .. read this -
http://sound.westhost.com/project117.htm

What you propose is dangerous, I actually design, layout and
build my own and I would be very cautious with a project of this
magnitude... you could fry an ELEPHANT with 200V DC!!:bigeyes:

Also, from a cost standpoint , even for a 400/800(4 ohm) W amp
(see below)
the transformer and capacitors alone would cost 250-300$.
The best transformer I've seen that is reasonable for
this range is....
http://www.antekinc.com/AN-152115.pdf
180$ shipped - 30LBS huge 1230w

It would be better to start with a smaller amp like DX amp
or my FA1 .. all + - 50/60 V (just a nasty shock) and
you would learn about basic push- pull amps.

I know many said to me " start with a headphone amp
or low power chipamp", but I think 100 watt amps are
safe enough given the right advice and design..

Here is the big one (7 pairs mosfet for safe 500w)

Seriously?

Hereís a tip, lurk around the forums for a few months (like Iím doing), start off with a small simple amp and ask questions about that, get some experience in building the circuits up, and then after a considerable amount of time attempt a high power amp.

Large amps (such as the one you want to make) can kill you / burn down your house if you donít know what your doing :hot:

You might also want to save your pennyís, as the components needed for such a large amp will be co$tly...

Last thing is what speakers do you intend to drive with such a monster? As it will certainly "let the smoke" out of anything less than monstrous

Saying all of that though, I think Iíve seen a circuit for a 1.5kw one around here somewhere. (use the search)

Hi Kim,
Some of us already have...or close enough to it. (see below - 2 of these bridged will easily do 1000 watts into 8 ohms)

Both of these outcomes can be accomplished with a smaller amp. Better to not take anything for granted, especially the electrical safety.
