Miniwatt N3 no longer making sound

Hi, I have a Miniwatt that one day stopped powering on. I have orange light on the on/off switch but that's all. I've popped it open and theres nothing obviously blown or burnt and all the wire connections look good, where should I start looking?

EDIT: Forgot to say I tried changing all tubes as well.
