Probably. If it oscillates, then the value is too low....

Thank you Mr Pass

Good morning, gentlemen.

Can the Tokin 2 SK 182 ES replace the THF-51 S in the Schematics?

 

[Nelson Pass]

Yes. It is similar enough with a little adjustment.

Bonjour, messieurs.
Pour le montage du THF-51S où puis-je acheter de l’isolation rose (keratherm) ?
Je vous remercie d’avance.

 

[Zen Mod]

its damn big, so silicon sheet is good enough

I know the 2SK77B are unabtanium, but I am trying hard to ignore that. Sooooo, where can I get a pair? Let me know if you have an idea (maybe by PM).

 

[Nelson Pass]

My last contact on 2SK77B was with Maxonic and FAL in Japan, and while they
gifted me some, the price on more was $400 each in large quantities.

I simply had to "pass", but they are very fine parts.

Is 2SK77B the 2SK77 in different case or there are other differences?

 

[R-K Rønningstad]

There is a picture showing both at this page #vfet Instagram posts - Gramho.com
The packages are different.

 

[Soundhappy]

Different chip inside 2SK77B has the bigger one

 

[R-K Rønningstad]

Do you happen to have data sheets, Christophe? I think I have seen those floating around.

Yes V-FET / SIT data sheets Have a Great Sunday

 

[R-K Rønningstad]

Ah, of course. I have already forgot that I downloaded those a week ago.
I think the 2SK-77B once was linked here 静電誘導トランジスタ DC アンプ B-1a - デジタルドメイン , but the link to the data sheet seems dead now.
