I bet they're there because of the slim chassis, it is easier to fit some small caps rather than a bigger one.
It falls into solid state category and I finally decided to share these photos. Maybe someone will be inspired by elegant shape and rich color scheme. 
Nothing special, it is just modest 100 watt subwoofer amplifier. The only interesting thing here is the 3 position power switch. Amp can be enabled by remote signal from main amplifier. Due opto-triac and power relay there’s no any power consumption in “standby mode”.

Nope, lateral 2sj162/2sk1058 dual pair mosfets. Sounds superb !!

Hi Vtystaat I'm in the cape at the moment, can you please say where you sourced these mosfets.
Thanks
I like the idea of having the schematic in the housing,
Wish commercial equipment would still do that.
Makes repairs easier.
Hi Vostro, I'm i the Free state, I got the mosfets from AP electronics, seems to be old good stock, they are a bit pricey, but it is good money, it seem to be the real deal, I have pushed the amp real hard , there are no problems, it's superb, the mids and high's are so much diffrent. I can hear stuff that I have never heard before !

Thanks for your nice comments...
I've heard my first Aleph3 about 10 years ago.
Since this moment i never forget this sweet warm sound.
The second unbelievable experience were the LS3/5a.
Now i'm 10 Years older and in my studio standing the dreams of my youth...
I'm sooooo happy!!
(I built about 20 Amplifiers, but the Aleph was the crowning project...
it will be hard to beat this ensemble)

Very impressive build entenschreck. Looks like a fairly massive amp, and I'll bet it sounds just as impressive. Like your simple 2-channel rig setup too....this is my newest solid state project: a Pass Aleph3 pure ClassA amp.
