nope

look no further then BA3 Bal

Pa will give ya tiny puzzles about biasing , no need for moi to rape peanut brain

however - his Sony amp is Demonstration of Force ( as many other recent pieces are)

for moi - using them as followers = waste of parts - considering that he's able to make the same with plain dirt mosfets

I'm not sure will he admit that , or not

It says MOSFET. But these devices should be VFETs. Are these really original Sony parts? Anyone bought from this vendor?

If they are real, then I think you can use them, keeping in mind that they
have a lower power and current rating, and about half the transconductance.

It might be that the 2SJ29 and 2SK82 are the same chip but two to a case,
it's hard to tell.
