Help! I have an Orange Micro Dark Amplifier that won’t turn on. The ‘on’ switch spins, and I can push it in. I’ve attached pictures and a video in the text below, can anyone tell me how to fix it, or if there’s anything else wrong with it? Thank you!

Beginner’s question… I have 14AWG cable that is General Use. Would class 2 be better to connect a 400w 4ohm minimum bass head to an Acoustic B410 cable that is 8ohms?
