Hello,
I like your design. Very clear.
Will you engrave the front plate, like mefinnis?
What are you using for top cover of your enclosures ?

Hi Rodd!
If I say that I`m enjojying everi note coming from my Manepan`s fided bay the amps, and asuming that sound will get improuved by time (only 20 ours till now) I said all. But if I try to submit - bass tight fast and dynamic going so low as Planars alowing, mids are cristaly clear and (not just a phrase) full of ambient details, higs open but newer anoing. You shoud heer the brass section on Hose Alberto CD. Pure salsa. Stage is width, deep and high compared iven with HQ tube gear. Beautiful. There is no field in frequency scale coming out. Linear and natural.

Mark hi!
Realy glad to hear from you. Like I told on the top - thank`s again. Your help was crusiall to me.
Chasis? "With a litle help of my friends" said Joe Coocker.
BTW for all of you without a proper education and expirience in the field of electronic (like me), starting the project like this (or maybe smaller?) it is great learning proces. Do not be afraid to try. It is a great expirience to turn that main switch ON and hear the music.
Mark, that Aleph 5 - stuning.

feet
Since nobody has made a comment about the feet, I would like to make a suggestion. I learn this from HPotter/Peter Daniel. Cut eight 1" length from a 1" diameter broom handle (or aluminium, since yours looks so good) and attach it to the bottom plate of the 2 amps. It works very well.
I'm assuming you're still waiting for the feet to arrive.
