Hey guys. I decided to build my first CMOY recently after reading up about it for a while on Tangent's site. I followed his tutorial exactly and bought pretty much exactly the same parts/board etc. I plan on getting some Beyerdynamic DT770's to use on it.
I have never soldered anything together like this before but i'm quite pleased with how the soldering turned out. I tried to use as little solder as possible and tried to prevent solder bridges by using a stanley knife to cut a little groove between all solder points that were'nt meant to be connected.
Now my problem is that the right channel isn't working at all, not even any noise or anything. The first time i tested it the left channel worked but was popping/noisey. After cleaning the pcb and making sure there were no solder bridges it now sounds perfect. But the right channel still shows no signs of life.
For the voltage readings, there is a slight difference between v+ and v- of about 0.1v. I can't be more specific than that as i'm using an analog multimeter. Using two 9v batteries, v- (left) reads about 8.1v and v+ (right) about 8.0v.
Will this have a significant impact on what's going wrong? I'm hoping it's just bad wiring with the cables and not anything too tedious.
I'll try and get some pictures up of the front and back of the board a bit later.
Cheers for looking.
note: it is not yet mounted in an enclosure if that makes a difference.
