Ulyanov currently manufacturing the 6c33C?

Does anyone know if Ulyanov (or any other factory) is currently manufacturing the 6C33C?

I suppose, that the brand Phase Style Ltd (PhaSt) know this, because this brand are located in the Ukraine:
Phase Style Ltd. ::: PhaSt amplifiers ::: Verstärker ::: PhaSt triode SE ::: Deutsch (German language) or
Phase Style Ltd. ::: ï³äñèëþâà÷³ PhaSt ::: Ïðîäóêö³ÿ ::: PhaSt triode SE ::: Óêðà¿íñüêà âåðñ³ÿ (Ukrainian language)
