I have a question.........

halvardf · 10th September 2002, 01:45 PM

I found the schematics for Anthony's (www.aussieamplifiers.com) Symmetrical 400w amp. I have now redesigned the PCB (short of money) and made it myself. And now the question: Can I publish my PCB layout in this forum, or is it ilegal due to Anthony's copyright?

Best Regards

You should probably ask him.
just out of odd interest, did you make it solely to save moeny or did you do anything "special" ??

I have tried to send him several email, no reply at all. Maybe my email's didn't get trough.

There were several reasons why I "cloned" the amplifier.

First of all, he didn't share his PCB layouts, so if I would make one, I had to buy the PCB from him.

Second, I have alot of 100x160mm PCB cards and I would realy like to use some of them for a good cause. So I made a layout so satisfy my goals.

Since I had the PCB cards, there was no cost's with them, and I had some spare time to kill, so what I tought why not.

Then I tought he maybe had a reason for not sharing his PCB layouts, so I tried to send him an email, but I got no reply. And since I have seen him here at the forum. I tried to get in touch with him here. And I also though that I could get someone else thought on it.

Anthony says in the construction notes that it's an update of a design that he published in Silicon Chip (aus) in 1994.

maybe thats the reason why you cant see his layout.

I dunno.

I have read the Silicon chip magazine. It contains a picture with silk screen on, and a very bad picture. So, I have never seen the PCB layout.
