Hello,
I am surprised that you are not satisfied with the tubes. I saw the photos and indeed there are some minor differences in the internal walls of the tube but the tube is the same, having the same characteristics. Please test them in a working environment to see for yourself. They are the same 1579 tube as is clearly seen on both tubes. Please let me know how they work and if you encountered any problem with them. These are one of the best tubes in their class and they have been matched for best performance. Don't mind the interior walls, those are not important, performance is important. Cheers.
อาาาา เค้าจะบอกกลายๆว่า มันคือ 1579 ที่เปลี่ยนโครงสร้างไปเป็นแบบ 6n9s รึ
