Hockey Puck SIT 2SK180 by Tokin source NOS

Is one more desirable than another?

 

[Soundhappy]

I keep saying. Get them while you can, there's going to be
more projects in the future, and the supply is low.

Any of them is the answer.

I bought a set of the SK180 and they arrived today. Thanks to @Soundhappy for pointing me to a good seller.

Now I just need a recommendation for the best project. I have THF-51S going into a SissySIT, so maybe a Singing Bush? Recommendations appreciated.

I snagged a pair of the THF-51S devices as well. Been curious about the SissySit, so these will probably go in that. I also have a pair of 2SK182E for the Singing Bush, and a pair of 2SK180 for a DEFiSIT variant of some sort.

Diyers can buy 2SK180 matched quartet's for 75Watt's Vfetron amp.
Cost is going high!

Does the bin [?] of the 2SK180 matter? I've seen suggestions that the D is desirable but with no accompanying rationalization.

The reason is because the C and D range Tokin batch was a curve tracer tested by friend Jama and with Dady amigo collaboration.
All shows us relative consistent characteristics, if you get a pair from the same box.
Anyway, today you can get matched Sit's from verified seller's , was not that easy a 5 ~ 4 year's ago

[Zen Mod]

they really look as real thing , but you'll know what you got only when you get them

that's that with (still) unconfirmed sources

 

[woofertester]

Matched pairs require a large population and a seller who can actually match them.

These guys seem to have a lot these SIT devices. There are also other offers with photos showing testers doing some measurements. Easy to find among 10 or more offers.
