Sir, you may not understand my purpose. I want to make it sound softer. The hearing curves of each of us may be different, and not everyone can perceive the subtle differences. Thank you very much for your reply.
Have you built the amp yet? If not , how do you know if you want it to sound "softer" - whatever that means. Build the amp as designed and listen at a lower volume setting if you want it softer. Anyway, the speaker may have more influence on the sound in your listening room.
I'm using BC556; though, BC560, or any other "universal PNP transistor" can be used there, it's "just" cascode, so far from critical
any suffix can be used, or no suffix at all
For some reason I thought I had these for J2. I bought them a long time ago. They were being phased out and everyone said get these while you can so I did.
Oh well, guess I can use 150 parts, have those too.
I would have sworn I bought these for J2, but it has been minute.

to clarify what I meant
as long they are SJEP120R[*] you're good...... whatever numbers you have as [*] , who cares .... ZM is happy with any of them
so, if you have them (any), you're good and use them as lower one in OS
if you don't have them, be perfectly happy with both IRFP in OS
magic of F8 isn't in Semisouth part (it is just partially) but in everything (else)
heh, it's almost good as M2
didn't you show pic of 2 SJEP quartets, somewhere around?

Choky, you either haven’t gone to bed yet or you are up really early😂😂😂
sorta leaning to meet with normal people cycle, so had short nap early in the evening (couldn't see anymore, eyes shutting), now taking up to full dose of mental activity, and going to zzzzzzz again
who knows, with some luck, maybe I'll wake in somewhat normal time
though, normal for normal ppl, ZM Omninotnormal
One set I got from Semi South. The other was group buy Euval? Been a while now. I thought it was for J2 purposes, who knows.
Let me attach better pic.
