Hi all,

I've just uncovered what I believe is an old Hill Audio Powercube from a relatives house.

It does seem to work for a while and then starts to make a loud buzzing/distorted sound. Cycling the power temporarily solves the issue but repeats.

I have attached a video below and I'd appreciate if anyone could help me diagnose what the issue is. I'm not particularly familiar with PA systems/speakers in general so I'm lost!
