To me, it looks like just a functional sample. If it was a serial production piece, then the factory quality standards would be very, very low.
I agree. It must be a very early sample/prototype as the placement and soldering in general is
very poor, letalone the cleanup (or compete lack thereof).
I look at the photgraphs of the interior and think, well, they used the base grade Nichicon 'audio' caps, just FW, not UFW or UFG. Sure they all get a nice 'gold and black' jacket, but give me UFGs anytime. They cost more, but are way better for coupling AF. I know, I use them.
And, the vent crimp is not typical for Nichicon, especially for those values. The Chinese copiers haven't worked out Nichicon's vent crimps yet.
The pot may, or not be genuine Alps. Let's get a closeup and see.
Basically,
everything coming out of China is suspect at the present. Let's not kid ourselves. All componentry could be 100% real or 100% fake. The huge amount of fake capacitors is unbelievable. I see them all the time.
And that 'Rubycon' main filter capacitor- there's so much wrong about that, I cannot even go there.
