I have upload the documentation for the DRV134 pcb. Can be found at the wiki page and here

I will order parts today and plan to start making kit's next week and I won't mix the parts so you won't have to worry about unmarked caps. I will colour mark the small parts.

I signed up for 2 DRV134 boards and updated the Wiki accordingly.
Thanks!

peranders: I am a little confused. What is BPA300 compared to PA 150 compared to DRV134 ? I am interested in a litte more info. Be aware, I am a novice from Norway, but I am 120% certain that I can put together a module or 4

The single LM3886 pcb is called PA150 and two such pcb's driven by a DRV134 is a BPA300 amp. You can check the webpage of the designer http://shine7.com

Ahh... Now I see. So the BPA300 delivers around 150W into 8 Ohms?

Hi Peranders,

Is there kits available for the DRV134 pcb's now. I'm confused at first you said there wouldn't be any but now it seems there are.

If there is can you change my WiKi to add the kits with my order. Just paypal me the difference.

Also one question, the rectifier is on board already, how much voltage is needed to run the DRV134 unit. Can I splice it from the big transformer (BPA300)

Thanks for your help... JohnnyP00

The SMD parts are for the PA150 pcb. I'll only offer the IC DRV134.

You can check the datasheet for the DRV134 if you want to know any details but if you use the on-board regulators you will need 17 volts at least if you use the LM317/337.
