Hey guys! Thanks for the great help posted on this thread! This is my first post on Head-Fi, and I apologize if this has been discussed elsewhere, but here it goes.
Today I finished DIYmodding an iPod 5g. I put 6.3v 47uF Elna Silmic II caps inside (with the positive lead running to the DAC) with the help of Tarkan's CF adapter, and ran silver wire from the pads to the dock pins.
After closing it shut, I tested it with a multimeter and was shocked to discover the DC offset reading .5 volts on both channels! While not identical, L and R were consistently high and the measurement seemed to spike to 1.1 volts when the + and - probes first made their connections. The AC voltage measurement moves to the music so at least it appears to somewhat work, and the headphone out still reads 0 mV.
I don't want to risk plugging it into any amp, at least not until it's down to safe levels. Could it be that the caps are charging up somehow? Maybe putting in resistors to ground would help? What do you guys think I should do?
Have a nice day!
