You can use the circuit but Tokins deserve hardware scaled up, so figure on different kit.So is this for the big Tonkins also or is that still coming later?
YES!!New boards can be optimized for 2sk82 2sj28 with change of two resistor values.

Hey enjoy next DIY amp's future build round with powerful Tokin triodes from Japan

Awesome news and thank you Mr. Pass! I'm fortunate enough to have a few of all four types and I'm hoping I'm lucky enough to get one of your kits especially since I've had the K60 and J18's sitting around for so long the cans are starting to grow moss. 😉New boards can be optimized for 2sk82 2sj28 with change of two resistor values.
@Soundhappy I meant to say that I don’t have a stash of Sony.
I’ve spent some Covid money on those Tokin.

Reminds me of how I spent some of my student loan money on a Nikon F3 back in the day. 🙂
Perfect! I was hoping for that. A board that can use several VFETs, with value changes for different transistors.New boards can be optimized for 2sk82 2sj28 with change of two resistor values.
Thank You, Mr. Pass!
This thread will save hundreds of crippled Sony TA 4650/5650 sets around the world, to be used as a Vfet power amp eventually. Now I can put my J18/K60 to good use.

Well spent money 🙂 You get some triodes,@Soundhappy I meant to say that I don’t have a stash of Sony.

now that is potential for interesting amplifier ,
Tokin can drive less sesitive speakers.
Happy new year to all!
Does it mean, that it will be only a single ended designs, not a Push-Pull with complementary pair?

This all about SE or aided-SE.
And some FOMO in the grand scheme too.

Yes. In order to maximize the number of amplifiers, with only a few transistorsHappy new year to all!

there is only 1 VFET per channel. Previous efforts were push-pull, but this is
likely the last go round with the Sony parts.

Thank you for the effort on this project; I been hoping for years for this 🙂.
Has it been decided yet if release will be by lottery again, or by first-come first-served, or ?

Since we are not providing the vfets, there is not much limitation on availability. We will just run them through the store.
I ordered 300 channels of pcb and transistor bars.
