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

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.

I like the 6550's too, and use them in my VTL 450's. I'm just thinking that if I can increase my current stock to enough to put in the VTL's (7 good ones, increased to 16), I can have a listen for myself, for not too much $$$$. Thanks Albert.

Peter, what was the out come of your KT-88's? I have the recent discontinued VTL-450's and planning to retube with Wing "C" tubes. I am also researching the Reissued Gold Lions (New Sensor). Do you have any info.
