One up and running, not a complete board but still, they are working

Click the image to open in full size.

I had no LM337T so the cables on the right side is extarnal -15V

Due to other lack of components I where only able to mount one section (of 3). I also had to skip the buffer at the input.

Im using TL071 instead of LF411 at the servo-circuit, works great. I have also skipped the resistor at the output, not needen when only one LM3886 is used.

Listening-impression is great and simular to rev 1. Although I have only used an mp3-player as source. The heat is no issue, you can easily thouch the LM3886 after 20 minutes of full volume and keep the finger there. I would guess it's temperature is arround 35 celcius.

Calle,
nice to see ... still my questions for once more:

Due of waiting ... would you share your gerbers or even eagle files of both versions here (with/without 15V supply) ?

Do you have a link to your swedish forum to get some more impression to your board / Layout ?

Would be very nice if you would / could / want to share it

I'd appreciate your answer
Thanks in advance

Regards
artQuake

The boards are made by me in Eagle. Ordered the PCBs from www.pcbcart.com. A good source that is reliable and fast with good support.

Im still happy with the boards but have noot ordered any more. I will soon, but I have so much work now. Im working in Sweden one week, then in Belgium next week, and I will do so for 2 months time now.

Here is latest image of one board that I play on daily. External +/- 15V still since I have not ordered any LM337 yet.

Calle - these boards look really nice. I am glad to learn that your project was successful.
Do you have any plans to offer these boards through a group buy or on your website?
Cheers!

Thank you dudainc.

Yes I will offer them for sale at my webpage in the future (by using Paypal). I still have some work to do with the webpage and I need to order boards.

I will not arrange any groupbuy.

Cheers!
