"Another way to emulate a tube triode by the FET"

[ricothetroll]

Hi !

I found a link to this article on groupdiy.com's forum :

http://milas.spb.ru/~kmg/tubeemulation_en.html

Has anyone here already tried/heard it ? Anyway, this looks like an interesting thing to discuss here I spiced it, its harmonic content resembles the one of a 12AX7, at least up to the 4th harmonic.

I'll definitely give that one a try when I'll have some time !

Best regards.

Discussion topic, devoted to my devices is here:

Anyway, now I moved to original Victor Kampf idea of tube emilation.
Example of using this idea:
http://milas.spb.ru/~kmg/jcm800fetLnd150_en.html
In this design I use high voltage (500V) LND150 lateral mosfets.
At bottom of page you can find comparative samples of fet & "glass" versions.

Hi Mike,
Those are such nice projects ! Thanx a lot for sharing them !

By Victor Kampf idea, are you referring to this article ?
