Heatsinks for Bosoz?

[lpm76]

Kari, You are an artist! - Why not stick with the goldplated red pcb as in the Aleph-X-boards you did. They look awesome.

I'm up for a groupbuy no matter what colour it is.

Is the connection pads layed out for terminal blocks?

Steen.

Yep they are terminal blocks with a pitch of 5,08mm. However i will not use terminal blocks for at least the input and output, i mainly add the terminal blocks because of lineup when i do the drawing. Also if you want to use terminalblocks now you have to turn one of them 180degree to actually be able to insert the cables or you could use blocks where you insert the cables from the top.

I'm currently working on the powersupply and still ranting pcb fabs for better pricing.

We'll stick with the red soldermask. 😎

Kari, is the footprint for the heatsinks std. SK104, STS ?

Kari, any chance you could post a schematic on both the preamp and the psu?

Hi to all,

A view of the heatsinks used in my CCS-XZ-Bosoz
Good for 10 watts.

Regards.

Alain.

Did someone say heatsinks?

I've got to win the prize for the most heatsinks, and its not even X'd or CCs'd. FYI, I think these are identical to the ones on the PCB.

 

[steenoe]

Alain and Igreen; that looks great🙂 Something like I figured it ought to. My BosoZ runs HOT with clip on heatsinks, for sure.
Thats more like it guys😉

This is my BOSOZ, I would really like to build a set of Kari's new boards to compare the Toplolgies in my system.

steenoe,

Two more hot spots

1)- Attach the pair to the Chassis, good...

2)- And Better, attach the Heatsinks together, see picture...
now I have the same temperature on the 2 MosFets

I bought this case for my X-Bosoz project for a whopping 35USD 😀

I also bought two of their M-9 cases for my AX project for 115USD including the heatsinks!

Hummmm.. I guess some of us are really good at making boards and some of us are artists with metals and plastics. 🙂 🙂

Wow, you are a wizzard, Alain😉 Great work🙂

Here's the schematics for the preamp it self.

That is simple😀 I cant believe that would ever sound good😀 😀
On the other hand....😎 That looks great, all 610's, just what I like😎

You did a mini a ? Can i see pictures ?

 

[steenoe]

Jason, you can have a look at my crude Zen, and yes, it plays the trousers of any chipamp🙂 It sounds wonderfull😉 I threw it together last saturday😀 😀

Steen.

 

[jleaman]

Did you slice a power cord open for that wire : O ) Loks good Does it get hot or just mild ?

j'

 

[steenoe]

As a matter of fact, I did do that🙂 Take a look at this hardware😀
I intent to make a CLC PSU for the ZEN amp, with that. What do you think? Well, the Zen sounds so great, that I think it deserves a decent supply. I hope to get my mate, Magura to do me a couple of his nice coils, for it😀 Also I did today get some 6mm2 lead, that will be used instead of the skinny ones on the pic! I have great hopes😎

Steen.

BTW it runs hot, but not too hot😉
