Are my older Svetlana KT88's Svets or Winged C's?

Hello, I've got 9 older (e.g. 2002 or 2003) Svetlana KT88's. They are marked: "Svetlana Electron Services Inc, KT88, Made in Russia" and have codes such as 0012, 0010,0009, 0110.

I need two matched quads to try out KT88's in my VTL 450's. To match these existing tubes, I'd like to know if I should be looking for a set of Svetlanas or Winged C's. I am just trying out the KT88's, so I would like to find some used tubes (each can be biased individually on the VTL's).

Thanks very much, Peter S

Current production Svetlana KT88's are made on the same assembly line and in the same factory as Sovtek tubes.

Wing C brand are the same as your old Svetlana.

The Svetlana NAME (only) is now owned by Sovtek and associated brands.

Name change fooled everyone, perhaps not as well as the new Mullard, Tung Sol, Gold Lion and Amperex brands that are also Sovteks (or is it Electro-Harmonix? :^).

All built in the same place (EXCEPT) Wing C in Saint Petersburg Russia where they have always been.

Peter, Wing C KT88 is good, 6550 Wing C is good.

I use 6550 in my VTL's.

The 6550 Wing C is preferred by both Audio Research and CAT, I'm sure they tested before making the choice.
