Hi P-A
Got the boards last week in good condition. Thanks. Excellent boards. Was off for a week for Chinese New Year celebration.

Hi peranders,
Do I understand correctly ? You have spare PCB's from the Group Buy ?
How much would it cost me for 4 3886 PCBs and 2 DRV134 ? Do you still have SMD-kits ?
Could you PM me the total with shipping to France ?
Thanks,
Akira

Does anyone else have any issues with the soldier not wanting to stick to some of the soldering pads?? The SMD components seemed fine, but seem to be having drama's with the capacitors on the rear so far, havent tried other components as yet..
Is there something I can clean the boad with so that it might want to stick to the soldier pads?
Will contact cleaner do the trick?

The pads are clean enough but I think this is about soldering temperature and soldering time. The pcb has thick copper.
That could be quite possible as I am a little new to diy audio, with this being the second main project.
What temperature would you recommend I set the soldering Iron too for best results?

You can use up to 450 deg C for those parts that are connected to the groundplane. 350-400 deg C is normal I should think.
Ok I had it set to 360 deg C.. So I will try again with the temperature increased and see if that solves my problems..
2 pcb's left.
If there is any interest for more boards I'll consider a new group buy after the summer.

Hi Peranders, I would be interested in 4 pc of PA150 if you're going ahead with a new GB. Thanks.
Hello,
I have a question regarding the filter caps on the backside of the pa150 pcb. am i connecting one cap between pins 4 and 7, and the other cap between pins 5 and 7. (7 being ground, 4=V- and 5=V+)
What about pin 1, which is also V+?
I've tried following shine7.com (alexw88) pa150 backside photo but the caps cover the connections in question. I also looked at this photo, which doesn't seem to have the same connections:

if anyone could point me in the right direction I'd greatly appreciate it
