Hello,
I built a Crack 1.1 for my friend a couple years ago at this point. Recently, she told me that she was having an issue with it not having any audio coming from the left channel. She seems to have tried to troubleshoot it herself to no avail. So I got it back in to take a look at it myself.
Inspecting the solder joints, I saw that 10U seemed lacking in solder. I reflowed the joint with some solder and then ran the resistance check that was detailed at the end of the build manual. There were no inconsistencies that I found.
Immediately after powering it up, I saw that the led connected to A3 was not lighting up. Then when I ran the voltage check, I got off readings at terminals 5 and 9. Both of them read ~150V when they should have been 50-100V and 90-115V respectively.
Another thing to note is that the XICON 10W 3K resistor connected at terminal 9L had completely faded printing compared to the corresponding resistor in the opposite channel.
If anybody could help me figure this out it would be greatly appreciated! Thanks
