...right, not that much, but much enough for him to fire his amp with batteries. Often the last pieces of better sound cost the most money.

look for "JLH update"
...but i believe you, that your gainclone is one of the best sounding amps....if i have the time i would test..perhaps later...

ps if you plan to build: only use Mj15003 of ON, availlable at Farnell.
All transistors are matched.
Dc offset is a bit tricky to adjust.
i use jensen copperfoil in oil cap as couppling capacitor. you can hear each capacitor and resistor you change.
Hi ThomasS
Welcome on board!
I tried to e-mail you, but you have disabled the opportunity to recieve email through the forum. If you enables emails on your account i will answer your question.
But what do mean by "intgr. Xsoz" ?

my x-soz
i've been staring at Henrik's schematic of the x-soz for so long that
i finally had to give it a try. These are two mono blocks putting out
5 watts each.
first listen tonight and all i can say is amazing soundstaging
and crystal clear... and that was before warming up for an hour.
Thanks Mr. Pass and Henrik!

Re: my x-soz
-That sounds about right! (Until you try to make it deliver more than 5W...) -Extremely clear and transparent; resolution in the mids and top is scary!
I am in the progress of making a pair of 15-20W monoblocks of the XSOZ monster. As I have buildt a few SOZ's my expectations are quite high to this new X-version. If X-ing the SOZ is anywhere near Xing the BZLS......
😉
PS -Congrats moe! When will they get a decent chassi?

Nice job Moe.
Any particular reason for the placement of your chokes?
Was this the best position to avoid hum?
Personally I would ply the caps further away from the mosfets on the heatsink.
Again we will have to push you a bit to make a decent enclosure
but then again I'm sometimes as hopeless as you to finish a project 😉

I've noticed a distinct lack of stupid questions lately.
To remedy this here is my question:
Is the wattage output of xSOZ relative to rail voltage the same as a regular SOZ as shown on the Pass website?
I ask because the X Aleph appears to use about half the volts for the same output

I should say that this was a "proof of concept" project for me. I
wanted to see if i could build and x-soz and have it work. Thus,
the layout, the parts, etc. I am truly a neophite in building amps -
so please take my construction with a grain of salt! 🙂
(see Mads_K's P to P work for inspiration!)
As to the layout of the inductors - i've read on the Forum that when
placing two inductors close to each other, it's best to have them at
90 degrees. I have no hum problem at all. The amp is dead quiet,
with an unmodified BOSOZ as the pre.
I was trying to keep my point to point wiring short, thus the placement
of the 220uF caps near the FETs. I guess i was influenced by those
building GainClones and their point to point work. They have
power supply caps sitting right on top of their chips!
A lot could be done to make these amps "better" i suppose all the
same type resistors to start (!) and maybe a Black Gate cap for
the 220uF, some bypass caps in the power supply, etc. Maybe if
i can stop listening long enough i'll do that 😉
btw, i have no WAF problems, nor pets, thus i can get away with
having an amp like this sitting in my living room!

Hi Moe29
Nice work. Welcome to the world of X-SOZ.
Try x-ing the bosoz or at least raise the value of the output caps at your bosoz to about 50 - 200uF.
I am so buisy at the moment, I will be back later on.
Regards Henrik.

Yes, but as you mentiond, 4.25 Ohm resistor is hard to find. The reason I derw the scematic the way I did was to visualise the changes from Nelsons original scematic.

From my online dictionary:
monstrous: Shockingly hideous or frightful.
Exceptionally large; enormous: a monstrous tidal wave.
Deviating greatly from the norm in appearance or structure; abnormal. Of or resembling a fabulous monster.
seems to cover it............About the way my SOZ is shaping up
I dunno if the Pass amps want to be known this way!

Hey Moe 29,
Maybe you should do what I was considering for the SOZ- mount everything onto a piece of plywood and hang it on your wall.
Maybe monoblocks, hang one by each speaker.
"It's scupture/It's an amp!/It's a drain cleaner"
Wait ! Wait!!
Mount each amp channel on a larger piece of ply, but not in the middle. Then cut a hole in the middle and put in a full range driver.
Add braces to support it on the ground and:
Viola! Self powered open baffle speakers/sculptures

After a couple of weeks of listening to my Aleph 2's i went back to
my X-SOZ tonight... what a beautiful sounding amp. At 5 watts it's
not as visceral as the Aleph 2's, but it's crystal clear and dead
quiet... just beautiful to listen to. Now i know why Mad_K is
building a 20 watt version - i was thinking the same thing tonight,
a little more power and look out! I would love to compare a
20 watt X-SOZ to a 25 watt or so Aleph-X. Because simply put, the
X-SOZ is the sweetest amp i've ever heard.
