You can see it at Project 89 (under Projects -> Power Supplies) in ESP site (www.sound.au.com).
The project hasn't been updated since a long time, so several improvements have been made and I have learned a lot since I wrote it. I would like to make some changes to the article when I have time.

Enjoy.
Sergio

Sergio - any changes to the 3625 circuit that could easily be described here? I am building a board right now and would like to include any improvements you might have made while I'm at it. I am going to include a 100 ohm dead time resistor. anything else?

Well, the fact is that I am developing a design that I plan to sell in partnership with a company in the form of ready-built boards. If we finally decide to discard it for selling I will be very glad to publish any details here, but I hope you understand that I have signed an non-disclosure-agreement and that we can't publish any details by the moment.
As soon as we have finished some products that are in testing phase right now, I will be very glad show them here. They will be very good and competitive modules for audio amplification for home and car use.

Best regards.

Serg, I can appreciate your situation. I hope you follow through with it as it could reach a pretty large untapped market and get more people involved in DIY electronics. You could sell completed modules and Chassis in various forms allowing people to purchase them to suit their needs and put them together themselves. Kinda like buying a bare-bones computer in kit form. Good luck in your endeavor!
