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?

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
