Advice welcome..

It’s a good value and probably will sound fine. I have that chassis for my other amps. I like the volume knob on the right. Can’t put HP jack on left where psu is so it turns out the positions are quite limited in a low profile case like this. My one complaint is that transformer is too close to the amp board and it might pick up hum. The amp board should be made more compact and moved to the right. A smaller toroidal might have less leakage.
