Hi Soundhappy,
after you showing picture i was reading again any hours De-Lite thread yesterday, looking Michaels L' Amp part deux, searching for 1000W Halogen sticks......so on
Most interesting for me would be SK182- sharp curves.
Drive with low voltage/high current or vice versa.
I have seen pics you show a blue box with these parts- pulled out from old
machines......man. :eek:
But money...money...money...don't can dance everywhere...:(.
Triode Amp with the SIT.....dream on. :rolleyes:

Hi Bangla H

Light bulb needs adequate voltage rate, power, and resistance to work perfectly.
Absolutly the big SIT's are fascinating semi's.
Hope for new tested & verified class A schematics amplifiers to build.
Yes...dream on :)

@ Diyers

I see box of 2SK180 are gone :D :magnet:

1pc THF-51S TOKIN V-FET(SIT) (similar 2SK77,2SK180) NOS Original, Japan Made | eBay

1pc 2SK182E TOKIN Hi-Power Hi-Voltage V-FET(SIT) NOS Original, Made in Japan

Seller have the others big Tokin semiconductor triodes references.
Probably accept resonable offers and can make mesurements & tests for match pairs.
I just share the link. Personally i don't know if this batch are ok ?
Anyway new old stock sit's become very rare today :)

Wow, Soundhappy you actually have 4 x 2SK77's ?
They are really rare!
And they look genuine:)

Tubes do have a wonderful appeal. I have a SET using EL34's that almost
duplicates the SIT-2. Power, distortion, damping are very similar. Bandwidth
is wider on the SIT.

Carefully matched AB into a pair of OB Voxatives shows only small difference,
not enough to care about.

Of course that was largely the point of the SIT-2.
