High power amp

DavidWardlaw · 30th August 2006, 12:52 AM

Hi,

I want to build a high power amplifier. Does anyone know of any place on the internet where I can get a pcb with schematic/parts list for such an amp, or a kit? I'm looking in the 300+Wrms range.

I'd look at 41Hz AMP2 kit.

Note

The AMP2 is an advanced high power amplifier. Building AMP2, requires considerable experience in building electronic devices. It is not suitable for "beginners". If you would like a simpler to build, smaller amplifier, take a look at our AMP1 boards or the AMP3.

I have a fair amount of experience in building amplifiers. I've built a 1 watt and 10 watt amplifier and I'm working in my third amp (30W). It doesn't look so hard from the discription on their website. I've dealt with surface mount components before. Looks like a great amp to me. Thanks Ben!!!

If your in no hurry, Jan has some new amps coming out fairly soon. Look for the "TruePath" amp. It should be just what your looking for. 2x300w based on the TA3020 chip.

It should be somewhere around mid-late September.

While talking about high powered amps I’m after an amp to build kit or whatever about 1000Wrms mono or 2 channel to drive some mtx thunder 9500 subs 12v or mains.

Hi David

At the risk of been accused of marketing, if you want high power amplifiers have a look at the AV1000 amplifier or AV800 Amplifiers
The choice is yours

Another choice would be Rod Elliott
at http://sound.westhost.com

Just in case I get slapped by a moderator

Should not be a slap if your promoting both product's.

I vouch for the av800 tho. Great amp. Simple to build and great support from the builder.

Check out National Semi's BPA300 -- same idea is to bridge-parallel LM4780's -- note that when you parallel amplifiers the input impedance decreases so a preamp (or buffer) is probably necessary.

With a little ingenuity you could bridge-parallel a couple of the boards I had made up: http://www.tech-diy.com/chipamps.htm

The heatsinking is rather prodigious for this project.

The TDA7293(4) chips can do around 100W each and you can slave them together to get as much as you want (there designed for it too) as for a kit or pre-built board I'm not sure where to get them but they are a half decent chip
