About Matching:
It has the requirements and benefits of multiple tubes (4, 8, and 10) to meet your needs. Parameters are the same)
The newly engraved version uses the same vacuum equipment and metal material as the original, and is implemented according to the original tube technical manual, from the material to thickness of the glass bottle body and even the ratio of the pins.
New manufacturing process adds new age of automation machinery to make the quality and sound quality more stable.
Electrical properties such as high voltage durability and longevity are far superior to old pipes, and also improve noise suppression and structural strength.
Sound is the ultimate goal. The similarity of the sound is relatively closer than the old tube.
The sound quality properties and mid-range sweetness are very attractive and close to it.
The re-sculpted version is still a little delayed to the old tube in terms of thickness and warmth, but the re-constituted version has some advantages in terms of sensitivity and high frequency air. Overall, the re-engraved version is very successful.
