10w Xsoz
2 Attachment(s)

I recently finished a 10W version of Henrik/Nelson's XSOZ.

Many thanks Nelson and Henrik for your wonderful designs!

As the folloving pictures will reveal, I think this must be the (next) smallest SOZ ever buildt. High WAF was a deciding factor for me. The penalty for this is a firebreathing hot amp that runs all of the components on its limits, I doubt that it will last very long in its present condition, but tweaking/tuning will take care of that (I will have to scale it down a little power-wise).

The chassis:

Hybrid between Schroff Euro-Pac components and my own.

Here's the back. Nothing fancy, just ordinary good quality industrial stuff.

Here's an overview of the internal layout. Pretty tight.

PSU is made with a 600VA trafo, dual bridges and each channel has its own CRC filter made with 22000uF-0R22-22000uF.

Thank you Henrik!

I will be back later aswell. Tonight my X-amps are will be put through their paces. :drink:

Here's a pic of the XBZLS and the XSOZ together.

As to the sound I will simply quote Nelson:

"The Son Of Zen has a wondeful sound, very direct and clear, without the electronic veil imposed by complex feedback circuits."

(And that's before you X it) ;)

Mads! You're my hero : )

what a beauty! It is amazing the jump in dissipation from
5 watts to 10 watts. At 5 watts my SOZ runs almost cool on the
heatsinks i'm using... but at 10 watts, yikes! :devilr:

X-SOZ = coolest Pass amp to date

Could you please mail me the schematics used for your amp, including values for trafos and so on.

Im working on a collection of schematics of actually made zen series amps to post on a wiki page.

perhaps even include a short review of the building/- the result.
