As you can see from the pics attached the B1 board and transistors are from NP's First Watt store. The components are the standard ones used for these builds, all of it ordered from Digikey. If there is interest I can post a BOM but I worked off other BOM's, already posted.

The chassis is my own design. It is fabricated of 3" aluminum T-track sides, 1'8" 6061 plate aluminum bottom and back. The faceplate is 1/4" 6061, chamfered and polished. The case exterior measurements are 12" W x 8" D x 3 1/8" H. The faceplate is 14" W x 4" H.

I purchase the aluminum plate, locally, through a distributor that sells metal offcut sheets by the pound. I cut it all on my table saw, using a non-ferrous metal blade and coolant. All the fasteners are stainless except for the T-track nuts. I am working on a source for those. The feet were purchased online, they are an aluminum clad rubber 5/8" H x 1 7/8" diameter.

Thank you, if there is interest I might be able to cut up some more chassis. I'm not looking to turn this into a profit event, I have other sources of income. Included with the attached is apic of the finished B1 with a lexan top cover. The lexan look is starting to grow on me.

Hi Westend,

what kind of non-ferrous blade and coolant did you use?

Would you be able to sell me some customize cut aluminum plates, with my own measurement/dimensions? Let me know.

Thanks,

Fred

got them off ebay from a guy in the states at christmas time 20$ each shipped so i bought both

They are noble. Never used, brand new

I bought both, because i wanted to put one in the B1, and use one as a passive pre-amp so i can see the difference in the b1 and light speed and just a passive pot.

This is an update to my previous post in this thread, I just received a 50k TKD volume control from Parts Conn. , The pot looks and feels high quality, I hooked it up , And the sound is very good.

The preamp sounds so good , That I decided to give it attention to details as much as I can, So I upgraded the extension shaft, This one is from DIY hifi supply, It isolates the pot from the tension between it and the chassis, Also makes the feel of the pot really smooth, Compared to the rigid type of coupling.
