Hi,
I intend to build an Aleph J amplifier where I need two 2SJ74 transistors that I do not find or rightly say are very expensive from reliable sources.
Can anyone tell-me if I can use 2N5021 in their place or are they not equivalent? I'm not experienced enough to decide.
Thank you !

Replacement of Tosh 2SJ74
Niculian,
if you take the trouble of reading through the 34 pages of this thread you would have a taste of the sufferings others went through already when trying to find affordable alternatives to the discontinued Tosh's.
First advice is: DO NOT buy any "original Tosh devices" at prices of $3...5,-! It's all faikes even when offered by local dealers with seemingly good reputation.
A safe route used to be the diyaudio store but they are sold out and it sometimes takes ages before they get fresh stuff.
Remains the service of other diyaudio members who do have surplus stock of genuine Tosh's or LS. They offer these devices at fair prices. It is months ago I used such services myself so I am bit out of this scene and cannot recommend anyone without prechecking. In this thread you will find a no. of names who offered this in the past.
Actual drop in replacements do not exist so it will take probably elaborate try and error experimenting to find something half way working.
Good luck anyway

A part that may be easier to find is 2sj108; I used matched 2sj108V in my Aleph-J.
If the goal is an Aleph-J and you have trouble sourcing parts then I would suggest
ZM's Babelfish-J variation:
About possible Babelfish J interest

What is there to use BF256 as a replacement for 2sk170 in an LTP?
They are available genuine in Mouser, RS, Digikey or Farnell.

What do you use for the p
channel?
LSJ74, SST74
DMOS Switches, JFET Amplifiers, BIFET Amplifiers, MOSFETS

Modding and took these out from my Marantz CD 63SE HDAM unit. They are not match ...one is 12 ish the other 17 ish IDSS.
Are there SMD Fet's that are equal or close to these ? I remember seeing someone mention this long ago. Don't remember which thread it was on.

See links in posts 307 & 312
Ashok,
I think it was bf862, but not likely class of 170BL.
or perhaps BF245A,B,C -- which went to smt as BF545.
For Pchannel, maybe 2n5460, 2n5461,2n5462?

Thanks BigE and Itsmee.
I'm aware of the Linear Systems product. I was looking for the BF862 device.
I saw that quite a while ago. Wanted to see if my local supplier had it.
Maybe BF545 is also available locally. Will have to check it out.
Thanks guys.

According to this post..
Digit 7 should be curvy.
...Marantz used fakes with straight 7.
