I've been restoring a Paperboy cab for a couple of months now (I'm almost done). I've came upon a lot of problems and managed to fix them all. But since this cab seems to be cursed, a new glitch showed up last week: a sound issue.
As soon as I turn on the machine, you can hear this loud white noise, just like an old TV set on a bad channel. The sound comes only from the left speaker.
I ran the sound test in service mode, and it detected nothing wrong. I can also hear all the sounds playing normally on both speakers. It is as if this annoying noise was simply played on top of the music and sound effects.
I also replaced the AR-III with another one that I had in stock: same noise.
It cannot be the speaker itself because the "white noise" volume fluctuates when I turn on the service mode switch. It also fluctuates depending on the sounds played during the sound test.
You can check by yourself right here:

Could it be the main board?
I've put so much money and time into this cab, any suggestions will be gladly welcomed!
