I sought the specs on the tables published for many of the group and I start to look for them in the chinnese market, finally got 20 units and give 8 to the amazing but hide developer and tester Jama, he made and measured all the choices in class A like lamp unit with lamp, resistor, choke and CCS, I listen personally at his house in Cartagena and the sound was incredible and faster.
Contrary to all suppositions about its monster in capacity of 5nF it was a gain of near of 20 with a no limit of bandwide at least audible conditions, and also measurable. Tim sent another group of units and at the end we collect several with very good measurable curves, we have individual curves of all our units and could match they.
Another good impression related to its rouged indestructible both with temperature, current and voltage accidents when is was manipulated

The nice people at FAL gave me the 2SK77B's that Mike and I have.
Two thumbs up for them!
$30-40 sounds like a good price. Maybe we should do a group buy -
It appears that there will not be more Tokin SITs are NEC acquisition.

I guess group buy not necessary. I just bought some from watanabetomoaki
on Ebay. I'll let you know how they turn out....

YES + 10000000 Thanks to FAL Team
Thanks Papa for taking the risk.
Hope all sit's curves going up like they should.
Similar to 2SK77 and 2SK82 🙂

Hi Christoph, the price is near of 30 or near of 40? Can you make the bind with us? Could you share your address with us?
The FAL amp which transistor mount? 2SK77?
Thanks Mr Pass for your counsels and help!
Hi amigo Dady
Relax cool
Price is you who make offers to the seller how much money he accept.
Reasonable is to know if they are useful for linear amplification or is strange specifications curves batch.
Wait, maybe last news from Mr Pass is a big help for clear SITuation.
I guess FAL amplifiers are made with 2SK77B the same model was donated by the company.
Personally, I have ready collected 2SK180, 2SK182ES and THF-51S sit's models, but not from the same source.Was a + year ago.
Wishes to hobby amateurs we can have pleasure to build amplifier's with interesting rare bread semiconductor's.
🙂 Have a nice day

While FAL seemed to have access to quantities of 2SK77B, I am not
sure they used those for production. I was told that 2SK77B were $400
each, which might be the reason why.

After email contact with FAL and Maxonic distributor Sibatech.
Gentleman responds me, I can find only 2SK182ES so maybe this amplifier was made with?
Anyway find good verified nos triode semi's parts at less 50 $ is luck if compare
with the prices of vintage tubes and desirable quality output transformers.
Such transistor is quasi indestructible if properly used is+50 years of the lifetime guarantee

I stay tuned and curious about THF-51S performance from this source. Kindest regards

Discover first generations of transistors (TRANsfer reSITOR's)
were triode equivalent made in USA see page nr. 68 of " Electronic " magazine from septembre 1948.
Japan made vfets and sit's was updated modernised versions of this Crystal Triodes technology base
but not the first triode semiconductors every made
