Hello,
I just finished building my crack headphone kit but noticed two issues so far:
1) Voltage measured on terminal 9 was higher than expected. The guide indicates 90 - 115 V are expected, but I am measuring 165V. All other terminals measured okay.
2) The left channel doesn't seem to be working. If I pull the headphone jack out slightly I got sound from both channels, but this doesn't seem right.
Any idea are appreciated, thanks.
