it's better not knowing how many of these Papa bought

😀 I am less worry about short time " Adventures with SITS " Second photo is the shelf profile haha . Fantastic news!

 

[Zen Mod]

"first two shelves are ZM's"

Hello Gentlemen with these 2 SK 182 ES Jfets what is the most appropriate scheme?
Thank you in advance for your answers.

@ Toto34

Do You know excellent Michael Rothacher blog V-FETRON 75 UPDATE #1 | AudioMaker ?
Many interesting videos about Tokin SIT's in Lab Hangout episodes YouTube
Kind regards 🙂

Researchers at UC Davis (my alma mater) have developed new SIT using
Gallium Nitride.

It looks like Panasonic jumped on UCD's GaN FETs and put them into a $17,000 Technics amp.

Stereo Power Amplifier SE-R1

Their marketing materials describe stuff way over my head. The question I have is, are they suitable for a Pass inspired DIY design? 🙂

"driver"

mumbojumbo, most likely

anyway , we have enough small buggers to take care of and search for them , leave those to naive buyers

 

[coolnose]

Yes ZM, but those meters... you know, the Marcel Proust thing..

 

[Zen Mod]

oh yes , meters are seeeeeeeexyyyyyyy

🙂

 

[WBS]

My problem with meters is that at my listening level they barely move. So they're kind of wasted real estate! 😛

Interesting news thanks WBS.
Looks similar to some blue MKP capacitors less like classic transistor.
Who know maybe we get more GaN Fet's in the future something powerful like Tokin ones

This amp costs 17000$ - due to GaN Fet?

I doubt it. Based on what I discerned from the marketing material there are other tricks in their bag as well. I'm sure marketing has a lot to do with it as well. 😀
