JFET/MOSFET Pentode Emulation

Postby POTL » 14 Jun 2017, 21:20

Hello
Everyone knows that with the help of a field-effect transistor it is possible to simulate the operation of a triode, it is now actively used to create amplifiers in a box
But such circuits mimic only the work of the preamp
The terminal amplifier uses pentodes, there are not enough leads for simulating the transistor, are there ways of combining the transistor as mu-amp or something similar to simulate a pentode?

Hi POTL,

If you have enough time, there is a 40 pages document: http://www.davmar.org/misc/Fetron.pdf

Try search the web (especially images) using "Fetron tube" as keyword.

There is a couple of radio amateur articles: http://collinsra.org/home/album/solid-state-6au6/ and: http://collinsra.org/home/album/solid-state-6bf5/ 8)

Also take a look at this thread: http://freestompboxes.org/viewtopic.php ... eh#p227194

Cheers,
Jose

mmm
infact, jfet behaves just like pentode by itself
there are couple coversation on the net, about how to make "triode" of jfets


xquze my eng
have fun :wink:
