Default bugle phono troubleshooting

I just finished my bugle a few days a go. It worked fine for a day but now only one channel is working.

Is it possible that I broke the amp by wiring cables the wrong way? (I had one cable which had ground in hot and hot in ground) I think the ics cant be broken because I can hear one channel. If the capacitors are broken how can I check them?

It didn't work after, I thought first that only the wire was wrong (which it was) but then I tried with another cord afterwards and didn't work anymore.

It's most likely that one or more opamps are broken.
