I don't know if these are matched. New Tubes


Here are 3  New Svetlana SV572-3 electron tubes in their original boxes.
 
4th tube in photo may be bad but I have no way of testing it in an amp so it is free if you want it.

For Cary Audio and other ultra high end tube audio amps.

Also used in high end Class A DIY amps




These tubes are vintage and perfect for those who are looking to enhance their audio and video equipment. The tubes are made by Svetlana, a well-known brand in the industry, and are of high quality. They are ideal for use in amplifiers and other audio equipment. These tubes are sold as-is, with no condition statements,
