For those who love SIT transistors and are ready to pay high prices for obsolete Sony parts, here is a manufacturer of SIT transistors:

Pulsed Power SiC SIT | Microsemi

Moreover, these are SiC transistors, therefore more powerful and faster than the silicon ones.

This one is a bit expensive at $2,457.5967:
0405SC-2200M | Microsemi
and you must buy 5 of them from Avnet for a total of
$12,287.9835

But one can build a beast of an amplifier with 5 of them in parallel.
One could build a similar amplifier to FirstWatt SIT-1 which would put several hundred watts as output ! :eek:
 
My mistake, the second one

IJW120R100T1 - Infineon Technologies

is not a SIT but a power JFet.
It might still be used for audio, for example in a single ended configuration.
It's a tiny bit more complicated to use in single transistor amplifier, one might need to use negative feed-back.

With a SIT one can build a single transistor, no feed-back amplifier like this one:

FIRST WATT S1

which is the purest form of audiophile amplifier ! :p
 
Read label before using medication

Just took a look .... Interesting device and as zm points out, the naming convention is curiously similar to the semisouth 120R100. A word of caution though - the Infineon part is adepletion mode device. So if you just sub it into a design intended for the semisouth you will get errr fireworks.....
 
Very interesting device indeed :)

Just to add,

Hi Zero D
We don't have winter last season what bring the summer this year ?
Tomorrow sit diy amp projects in pipeline be play with Tokin 2SK180 or 2SK182
Greetings :sing:
