This is very sad and a lot of Single Power influence here, cheaper parts used in series and parallel.
I see the A, B and C markings so is there a PSU schematic as well?
Edit: Never mind, I found the thread and wow... google translate may not be doing some of those people any favors but there was some class A stupidity going on. Point to point always sounds better than PCB's!!! The Viva may be crap but it sounds so good with the X9000!! Yeah... might be because the X9000 is also crap? Just an idea...
Anyway some more pics from that thread:
Just look at this mess, hot glue everywhere (where they should have used lacquer paint) and cheap parts everywhere. Not sure why that woolen stuff and zip tie is on the selector switch but that is the ultra cheap switches I can buy at the local store for 2$.
Then we have this gem... why is a part of the shrink wrap on the cap missing and just what on earth is that supposed to be? A bridge rectifier? This might actually worse than Single Power but remember kids, a nice PCB with length matched traces sounds far worse than this!!
Now look at this picture of loveliness, a Rifa X2 (as in power supply suppression cap) ,known all over the world for their tendency to fail short (look up Rifa madness) being used in a "high end" amp. Not even Single Power stooped this low, he might have "tuned" the circuit by placing an Audio Note silver cap in series with an Orange Drop but they are at least good caps. This is just pure and utter garbage.
I just love this picture, look at that mess of wires into a bundle of solder. Extra price for the burn marks on the cap as zero fucks are given here. They should seriously have this as a promo picture.
Last picture and would you look at those XLR inputs... yeah that's one way of dealing with a XLR to RCA conversion... just not hook anything up to pin 3 of the XLR sockets. I'm sure there is some owner of this piece of trash that claims massive improvements when it is run balanced... Also, look at the soldering on that, I'm sure those RCA's came with nice ground tabs but nope, fuck it, let's just solder directly to the thread and have it leaking down and almost touching the center pin.
Lastly, I just love we are getting this from my good friend at JR Audio, one of the few builders of electrostatic equipment who is actually worse than this. I wonder if he's looking for pointers to becoming even worse?
