Firstly, I really hope you feel better soon. I have loved ones that struggle with mental health and I think anyone who is sane is also struggling. I am sure it is not the same as what you are going through. The world isn’t making it easy for anyone but the hateful right now. But I’ve got the same question. That is a huge tube relative to the rest of the amp and I am curious about the power supply. Any brand? Do you know what tube that is.

It's a cheap amp with an ungodly amount of harmonic distortion. Before I had that nobsound amp with two tubes and someone here told me to return it because there would barely be any good distortion. It's the one thing not directly recommended to me, but I like it so much better
