Hockey Puck SIT 2SK180 by Tokin source NOS

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.

Mr. Pass i find France produced germanium triodes was in the 50's.

Incredible story Mr. Pass and they was very beauty diodes who become germanium triodes à cristal 🙂

Care to Enlighten on the SE EL34 Amp

Tubes do have a wonderful appeal. I have a SET using EL34's that almost
duplicates the SIT-2.

Nelson

Is the EL34 amp your creation or a store brought effort? Perhaps you could throw us "tubeophiles" a bone with a few more details....please, pretty please.

 

[Nelson Pass]

It was a relatively inexpensive Chinese unit. It is no longer available,
but you can go to:

AliExpress.com - Online Shopping for Electronics, Fashion, Home & Garden, Toys & Sports, Automobiles from China.

and search for EL34 single ended amplifiers. They start at less than $200.

So your father was a germanium diode. 😉
I can understand everything. 😀

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 | eBay

400 watts | THF-51S is very quick triode transistor
only 50 nS switching time

 

[generg]

so you would prefer the THF-51S?

🙂

400 watts | THF-51S is very quick triode transistor
only 50 nS switching time

Less power, faster switching. If that's what you need....

 

[generg]

Thank you Mr. Pass!

Sylvain do you see it?

:--))

 

[Soundhappy]

Tokin is much more powerful and have lot of gain if compare to Sony vfets.
On the other side have more input capacitance and distortion.
Just curious about THF-51S and 182E potential in amplification.
Quick switching = better sound ?

Found this other Specs Table

 

[generg]

believe Nelson....!

🙂

 

[Algar_emi]

Do you mean the 400 watts | THF-51S?

 

[generg]

Yes!
