completely unknown, never used part
Unknown, new parts that NP likes. Sounds like uncovering a sunken treasure ship.
Soundhappy,
Nelson replied to you, long ago, that remaining transistors are all (supposedly) Sony parts:

He also said that: „The output stage is a follower, and has a socket for different front ends“

So, there were changes in design, as there is no socket on the pictured board.
He also said that this iteration will be closest you could get to SIT-3.

Add to that:
The last round of Sony VFETs will be followers, but special and unique
It’s going to be surprise
You will be amused
So, I’m sure we all will be veeery amused. 😀 😀

You think this amplifier is build with 4 pcs. of Sony in TO-3 package ?
You can re-read again , my question was about other not Vfet transistors 😉 Amusing
Nelson’s answer, on question what are other TO-3 parts, was “The few remaining Sony parts”. No other were mentioned. However, after a year, maybe he has different (even more suitable) parts in mind.
Anyway, one day we will know for sure.

Hmmm...
Surprise + amused = Surmused by Nelson Pass
Available soon at a diy store near you!

He is a man of many talents and a very busy one. Usually, methods involving pitchforks, torches and camp fires around his residence tend to speed up things a little. Maybe we can ask USA fellows to arrange something?
I still have a couple pairs of salvage VFETs.
Volcano names are nice. Singing Bush should be called "The Krakatoa". Maybe this one should be "Vesuvius".

Me too, those Vfet's in the drawer screams to do audio work and run's hot inside of the amplifier 😀
