In addition to Electro-Harmonix vacuum tubes, NS is also equipped with SOVTEK, SUNG-SOL, GOLD LION brands, and the other brands of vacuum tubes are manufactured in Reflektor factories located in the Dezaratov.
Electro-Harmonix vacuum tubing available here is fully aged in Japan with automatic sorting machines and is given a 13 digit serial number at the same time being accurately measured. (The serial number is attached to the box) Measured and matched and shipped. The error of the pair measured by NS company is often reduced by about dozens of percent even when tested in the same measurement conditions. However, in this high-precision selection, the error of the pair can be reduced to 5% (within 10% of pre tubes, depending on the measurement conditions).
Other than the electrical characteristics of the product (damage to other devices, such as bulb tilt, valve height difference, logo missing, etc.) are not covered under the warranty.

YM-1という当管2本使用のアンプで使用していますが、この管が一番音がいいです。ただし発熱が他の管より大きいので、アンプへの負荷も大きいと思います。半田割れ過去に一回ありました。

10数年前に作ったELEKITの真空管アンプ用に購入。交換後は問題なく動いています。

２本の内、一本は壊れた真空管と同じ症状で使えませんでした。違うチャンネルに差し替え４手も同じ症状だったので不良品かもしれません。まあ、結果一本は使えたのでよしとしておこう・・・
