I did contacted with the seller. I ask more picture from the actual item, from the other side to. Yes he wrote back but I think he does not speak English at all, or just I don't know...............
His answer had no meaning, he did not provided the requested information about the originality of the items etc.
In a short sentence (broken English) he asked me to go on and place the order.
Right now I do not have $100 plus shipping cost plus import tax fund to risk on items I'm not sure about.
I would not organise GB or participate until not sure if is orig or counterfeit......
There is no 100% money back guarantee, and what I heard to Visa you need to prove the item is counterfeit to act in your behalf.
No PayPal option

I I can not understand you.
If the item is counterfeit l lose my investment if I can not prove to Visa the item not orig. I read Visa ask someone when he asked for help if he is an engineer or technician to act in his behalf..
Or I lose half of it (that is how the company advertise) and keep the counterfeit item..
Please feel free to try your luck, DO NOT BE INFLUENCED BY MY experience or knowledge.

I'm rather wondering, is there anything what I can to do with my existing resources?
Namely, I have 20 2SK1058 and 2SJ162 by Hitachi. (or not, who knows?)
(Originally bought them for Borbely millennium power amp.)
Can I use them in this amplifier?
I hope so, because as Papa wrote:
"Toshiba Mosfets 2SJ201/2SK1530 or 2SJ618/2SK3497 would make fine
output stages, and lacking those, IRFP240/9240 would work. They would
require matching and some Source resistors, say 0.47 ohms, but they have
one advantage in not requiring regulated supplies."

according to be bottom of the page, two guys have recently purchased the fets. With any luck, one or both are people who hang around here and could graciously report on their authenticity for the benefit of the rest.. hint hint.

Kdi asked for upside down iteration of SE , with 2SK76 in output
so , previous iteration attached , too
ignore few differences in resistor values , not relevant

Bridging Boards
I was thinking of building 4 boards with 1 pair of K82/K28s each. I would then bridge two boards per channel ( +/- inputs).
The advantage I see is that I wouldn't need to match VFETS.
One disadvantage is that there would be twice the parts count.
Other disadvantages?
Thanks

These are no longer available from this store.
Looks like both the taobao and aliexpress sellers have increased their prices.
I looked again and it seems that taobao and aliexpress seller are actually the same provider.
That shop didn't managed to sell a single pair for the past year, but ever since it's mentioned here their stocks are moving quite fast (I know someone from Spain just ordered 12 pairs
).
