....I wonder if .... version doesn't sound exactly the same...if not better
There's only one way to find out - and that's why we are here !
...yep...let's build it.....There's only one way to find out - and that's why we are here !
I checked the link before posting, it worked. A few hours later, not.
I didn't download schematic, because it's there for years and also uses hard to find transistors, so I decided not to build it.
Also, posting schematic without author's permission is no-no.
Those are small laterals and there is no direct replacement for them outside of the same family (2sj76,77,78,79/2sk213,214,215,216). You could use some nice verticals like 2sk2013/2sj313 but the circuit had to be redesigned to deploy them (different Vgs/Id, different tempco, etc...).
...I don't have that Andrew...just a PDF with the project....if the moderators think it's best please remove the schematics.
IME, rubber, plastics, leather and denim can be highly degenerated, wood and metal pretty much too, and the glass will break first...
Original MOSFET s which used with USKOK are available in B+D Enterprises

Stupid spell correct.
Vertical is not a problem, but didn't know if the materials were similar to their larger cousins and could do with less degeneration.
Sorry Buzz, I still don't get it ...
What would you want to degenerate and what does it have to do with material (they are all silicone made) ?
Maybe you mean the MOSFET build type (verticals vs. laterals) ?
If so, why would you want to degenerate cascoding devices ?
Please try to be more specific, I'm still on level 1 when it comes to mind reading
Definitely don't want to degenerate anything silicon based.
On the lateral vs vertical front. I am currently playing with a pre that has the verticals as the main gain device and was looking into whether or not the laterals mentioned above had a more favorable tempco, allowing for less degeneration in the design while still maintaining stability. Didnt know if you had any personal experience with these particular devices. Bit OT, sorry
BTW, I am not sure I know what is going on in my own mind, so you not being able to pick up on it is completely understandable, although I do have high expectations of you
BTW,BTW, laterals=materials(spell correct), and lateral, silicon based things are really nice in just about any application i can think of and always are a pleasure to work with in a hands on type situation.

Aaaaah, you started counting from letter O...
Good !
You know the drill:
- open new topic
- post schematic
- buy a round of beer
- then we talk...
