Link to this group buy can be found in my sig below.

Please tell me how to go about ordering your boards. I am in America so there will be an exchange rate through PayPal. I am wanting enough boards to make two complete stereo amps. Parts in America are easy to get but boards are not.
thanks Pa,

Order six (6) BA150 PCB's

Hi Peranders, I would be interested in 6 pc of PA150 if you're going ahead with a new GB. I also posted to the BA300 ROUND 2, so I'm unsure which Thread is correct for
obtaining these PCB's. I do want six (6), to make one stereo 150 and one stereo 300
amp. Take care and thanks.
 
Ladies and Gentlemen

Let me put all the informations in one and a right place (group buys).

Basing on alexw88's (shine7.com) experience, I've created my own project of PA150 (3xLM3886). It has been modified a bit, the size has been reduced, and some other tweaks have been made. I'd like to share the project with you (below). PDF file with switchable layers, try it! I'm gonna order the PCB soon, if anyone wants to grab a couple of PA150 PCB, let me know. Of course, tweaks still can be done before the order.

PCB layout:

Power supply up to +35/-35 VDC. LM3886 datasheet.

I has been well tested by alex88. Testing and measurement:

It is still the same project, except the capacitors which were moved from the bottom to the top, C10 (10u) replaced with wima (better solution), and some downsizing.

Anyone who is interested, just give me your e-mail address and I will send you some details.

Of course don't hesitate to ask questions :)
