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.

Default fet

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