I’ve read through your entire blog and I’m thrilled to see someone had the same idea as me; build the amp from the book! Not that this was a terribly original idea. I’m pretty sure that’s what it was there for. 
I’ve been studying the specs and I’m sure I’ll have a ton of questions. Just like you, I’m going to start with the cabinet. Should be fun. I’ll continue to post here with questions and concerns.
One thing; I have no intention of bending the metal for a chassis. Can you recommend a good aluminum chassis I could purchase for this? Size? Specs?
Thanks!
