Wanting to build amp

systemerror909 · 24th June 2008, 07:26 PM

Hi, I've been on these forums on and off for a couple years. I recently completing a 41hz.com AMP 5, which was a lot of fun and sounds great. I recently was checking out this site:

http://www.chipamp.com/

and noticed that they had PCB's for the Aleph 30 for sale. Looks like something I think I might be able to put together, but was wondering where I could find some more information about it. Is this project something a relative newbie could put together?

Thanks

which aleph class A sound is good?

I think Zens and Alephs are easier to build than chipamps.

Thanks Mr. Pass,

I think I would agree with you. This PCB looks a lot simpler than the Amp 5 I built. Miraculously the amp sounds good, despite the messy job I did soldering it in the tight spots. Beats the pants off of Marantz, Rotel and Pioneer A/B class units I've owned previously. Can't wait to hear what a good Class A design sounds like now that I've got a better grasp of constructing an amp.

Any other suggestions for resources in building an Aleph or similar design amp?

Which sort of speakers do you intend the amp for?

If you can find 300 watt light bulbs, I suggest you try to build Zen Light or Zen V8. They're very easy to build and a lot of fun.

Currently my speakers are a set of Wharfedale Diamond 8.2's. Specs on these speakers are: 6 ohms, and if I recall correctly a meager 86 db/watt. I'm not too worried about a lower powered amp, the Marantz 2215B I was running them with a while back was more than able to provide satisfactory sound levels at a rated 15 watts.

It looks like the main two variants of Mr. Pass' designs are the Aleph and Zen designs, in a nutshell could someone explain the difference between the two?

In a nutshell:
Aleph= Commercial product
Zen= Pushing the limits projects, aimed for the DIY community

If 15W is enough, take a long hard look at the Zen articles at www.passdiy.com

Then go mix and match, to get what you think you want.

Presto! You got an amp, and most likely a bunch of ideas to what you're gonna build next

I think this was what I was really looking for:

New Aleph Mini PCB GB

So apparently BrianGT's diyamps.com site is down, which is why I couldn't find a bill of materials for the power supplies.

My only other real pressing question is: how important are matched transistors in this design, and where would I be able to find some?
