The tube store describes both of them as smooth. They're both Russian, but they're totally different tubes. Anyone tried both? Opinions?
 
Never heard of the Svetlana 12AX7, with the exception of the NOS version.

IMO the LPS sounds very good in V1 in a regular (i.e. non Roadster) Rectifier, as they are bright and can have the highs get out of control on the dirty channels. I would agree they are very smooth indeed. Very warm and round. By comparison, a Tung-Sol in V1 sounds kind of shrill in my Rectifier.

Hope this helps.
