One other solution is to use variac and change the output power by changing AC supply to the amp.. You will just use what you need. But I'm sure you won't need 50W.
50 Watt X Soz
Hi, one year ago i planned to build a Soz, 50 watts, too
I bought heatsinks for two Monoblocks, which costs more than 1000 $ (Euro).
I think i will go for about 30-40 Watts, thats enough.
I dont want to burn my House or the in house Wires.
Really, the parts for such a monster are very expensive. And since i tried Henriks XSoz with XBsoz i know i will finish these monsters next time.
here some pics, how i will buid them.
Design leaned on Pass....

Maybe I'll go with 30 watts too. I don't know.
I won't buy new components (heat sinks and toroids) at all.
What about the toroids? What is their approximative cost for 50 watts and 30 watts SOZ (2,4 and 1,5 kVA)?
Thanks

When you need to buy two of them, in germany you pay about 500 Euro/$ for both.
But then you need further the power resistors. I bought totally 64 pieces of 50 Watt Dale`s to share the heat to more of them.
1 Dale 50 watt costs about 10 Euro !!
Heatsinks, Resistors, Toroids and fine aluminiuim cases are the most costly parts.

Ralf, that's almost the whole amp. 😀
However, I know that the components are quite expensive... I'll start building it (don't know the power rating yet) in a far future, so I have a lot of time to look for components/bargains.
An another simple question: is a 10 amps wall plug good for a 50W SOZ monoblock, or there must be a 16 amps one as for Pass Labs X1000?
If a 50W SOZ monoblock draws 1200W, given Watts=Volts*Amps, it will draw 1200/230= 5,2 amps all the time, so there wouldn't have to be any problems for my house wirings. Is it right?
Thank you for your patience, as you can see some doubts always come to me.

...of course,
but i think the inhouse cables at least get worm.
if you go for 30 watts one wall plug will be sufficient.
in my listening room i can use diferent wall plugs, which go to diferent fuses, for each mono amp

Yes, that's right. But I have enough plugs, that's not the problem... my problems are bigger. Cost, dimension (placement), weight, WAF, skill for building the case (very hard I see), finding parts and maybe something else...
I think there's enough pain....

hi, till
i know how i can connect 2 torros, but how to connect three - where to pic up the middle ground when using three?
kannst mir auch persönlich mailen, my english is not the best....

..yes, it will be a heavy duty mechanical job, you need equipment for making it. a solder gun, only is not enough. and you will need any Euro, the more power, the more expensive.
I calculated my X Soz for about 150 to 180 lbs -per channel!
I think a aleph x should be as good or better, and way cheaper.
Next time i start building my first aleph x.

An Aleph-X?
I don't know, do you think it's better?
If a 50W XSOZ is too much for me, I would think about scaling down the output power, not changing amp.
I haven't looked at Aleph-X yet, is it still no-feedback?
I have to decide carefully, I thought that SOZ was the "cleanest" Pass Amp (simplest ecc. ecc.), with the only problems of little power and low damping factor... isn't it right?
I know that there are several versions of Alephs too...
I'll take a look on the thread.

Little power and low dumping factor are not problems in itself, the just reduce the number of potential "marriages" with loudspeakers... they need the right mate... but you already have the right one.😉Giacomo Pagani said:

Do not make a 50 watt SOZ or XSOZ. 20 watts is the most you should make. Beyond this it will not play much louder. It just makes lots of heat. And making a 20 watts SOZ is still fairly large to make.
You're right Roberto, I know that I've got the right speakers for a SOZ. That's why I'd prefer it to an Aleph.
I'm seriously thinking about scaling down the power rating...
Maybe 20 or 30 watts, as Gnomus said.
I'd prefer something more than 10 watts, Ralf, so I'll be sure to avoid problems while listening to my favourite rock groups 😀
I don't think that 20 watts is impossible.
As usual, thank you all for your kind attention.
