PapaSits ...... certainly , but I'm doubting that he collected ancient ones enough for trouble-free production
By using the rare SITs, the article(s) will be educational for something else down the line, like the Nemisis and Pass-1 SIT, semisouth, etc. That's my guess. 😉

@ Diyers
Upcoming article have lots options
we can build 4 differents mono amplifiers with:
1| simple pair of vfets
2| two pairs matched vfets
3| simple pair of depletion complementarys
4| two pairs of matched depletions complementarys
+| with 4 matched vfet´s pairs for mono maybe ??
I smile about fun choice of candidates not vfets as well for Mr Pass topologys.
Best regards

Part 2 is nearing completion. It is a mini version of the VFET amps that Sony
has been using at shows.
It can be built with 1 pair of 2SK82, 2SJ28 per channel or 2 matched pairs,
so you may want to get some of the last of these out of Acronman while
you can.

But seeing this I have some questions:
@ WalterW
?
😀
I belive they we have photo of prototype for demonstrations ?

that component is thermal fuse , I believe 70C
just in case if you forgot your pillow on amp ....... or if your cats are happy sleeping on it, just as mine are
regarding cap question - clarify ;
you want FW SIT1 sch , in public ?

Zen long ago I had a class AB amp that took about 2 hours to really warm up and sound good. But I could throw a blanket over it for about 1/2 hour instead !
The circuito es fácil, so inefficient Mr Sound. Avoid to use it on Europe, we are conservationist.
The guy who ask questions are WalterW 🙂I think Soundhappy is referring to the big loops of green and blue wire.

One possible response are :
This longer loop wire are nice if after 20 years someone
must change old capacitor ,
easy solution to manipulate pcb if need.
Less work with desolder.
Smart FW 😉

Before any more damage is done, please enjoy the weather, find a patio and grab a pint. 🙂
