Hello,
I fit a 3 pin plug and tried some transistors ..
I get a good result with a C369 ...
Any comments?

I did not find my stock replacements, but have a box of spare parts
from ?? all kind of old electronics ... ;-)

You need an N channel JFET. Only replacement I have seen is an NTE312.
Radio Shack used to stock them in the stores, now only online.

Here is a tutorial on the junction field effect transistor or JFET:

I've got the 2SK152 datasheet on my ftp directory on ftp://ftp.eskimo.com
in the user directory for "mzenier", "Sony2SK152.pdf" . (They moved stuff
around on my ISP, so I don't remember the full URL).

It was designed for the head preamp for VCRs, so maybe the OP can
arm wrestle somebody for an old Beta VCR and find one in there.
Extreme anti-static precautions apply.

There was an small outfit that used semi foundrys to produce a variety of
small signal FETs and other strange stuff (at a price). I think that
they had the 2SK152. "Interfet"?
