Any informations about price range of this new generation ISO chokes and OT ?
The price is not the same in different region.After I order these trans,I think the price is almost like the old ISO-Tango products.The new ISO won't product many kinds of stuff like usual,because of the age and health problems of 3 peoples.
would you know what core materials they use? Z11's or something else?
are they C-cores or EI's...?
sorry for the lots of questions....
All of new ISO output trans are C-cores.Like the old model XE-20S rename in FC-20S with C-cores.

Hi Guys
As a matter of fact I will be getting my new Tango Interstages NC20F II within the hour (I think the very first in the Netherlands 😀) handcarried by the shopkeeper my friend and audiobuddy.
I have built a clone Ungaku with standard try out interstages (did not make my mind up yet)...so no real magic yet.
I hope I will be in for a surprise.

I'm using the old ISO company (I wish they changed the name for the third company, it would make it easier to distinguish) NC20, if these new transformers are similar you will love them 

Seems like the new production team cannot get permalloy cores... at least i cannot spot any in the range

Didn't only Tamura do permalloy?
I hope I will be in for a surprise.
Erik, how did it turn out? Was it a nice surprise?
This is out of topic...A japanese transformer company Someya Denshi, listing mcintosh unity-coupled type trafos. Their top product ASTR-08 is trifiler. I don't know if they can ship oversea or any distributers. "http://www.someyadenshi.co.jp/HP/audio"

At least Hirata Tango did permalloy, too.Didn't only Tamura do permalloy?
