JFET MM/MC Phono Preamp

[schillg11]

Hello,

i am looking for a replacement of these JFETs for a JFET Phono preamp, which is the missing part of a 80's Hafler JFET preamp. Since most of the JFETs are obsolete, or only available at moon prices, i am asking the experts for alternative available FETs, I have attached the schematic of the right channel, the left channel is equipped the same.

Any ideas to complete this prepreamp??

Best regards
Günni

Nice circuit, no substitutes.
And you need to match Idss as well.

Hi Patrik,

that's the reality i expected!!

Maybe i can find an eqipped phono board from a Hafler SE-100 or from a Hafler 915 preamp, Both have the same circuit

So, if anyone has this phono section board left over, i am interested (PM please)

if you are desperate, you can try linear systems:
Linear Systems || Products

they make devices that make come close.
at least it is better than nothing ...
good luck!
