Hi renjiish
What's written on that transistor?
Is it
S2435
TI122J

How do you know it's a fet?
What brand and type of amp do you have?

Greetings

i removed it from voxson,italian made amplifier.on the pcb it had given the sourse and drain markings.from that i understood thatit is an fet.so i replaced with 2sk163 from hitachi.it is working fine even though the treble quality is degraded. if i can find the original replacement it will be very helpfull for me.

fet

Just try a Bf 245 B; this is the typical european j-fet, it should do for most cases.

thank you very much sir.even iam planning to use bf 245 b.what about using J201.many people are recomending j201 for preamp input stage.what is your opinion about this one.
