I Like that big black one, wow! almost 220mm of diameter... it is a 15'? And that amp with acrilic case, wonderfull work, hope you don't mind if i copy your idea on my amp!

I saw one of your pics, there is a SMPS, i never built one, do you have anyone that is simple to build for a starter on SMPS?

Thanks in advance!
