2000年頃まで全てのSvetlana真空管はSロゴで、露Svetlana JSC傘下でサンクトペテルブルクにあるSvetlana工場で生産され、流通は世界総代理店であった米Svetlana Electron Devices社 (SED社)によって行われていた。
Sロゴ商標は、2001年にSED社が倒産した時、負債整理のために米New Sensor社(NS社)に売却された。この頃からSvetlana JSCはSvetlana工場で生産する全ての真空管ロゴをСロゴ (Winged-C)に切り替えた。
このSロゴSvetlana真空管は露サラトフにあるNS社のReflektor工場 (SOVTEK, Electro-Harmonixブランドと同じ工場)で生産され、NS社がSロゴSvetlanaとして販売している。
ここで購入可能なSvetlana (S Logo)真空管は、国内の自動選別機にて十分なエージングを行ってから高精度に特性測定されると同時に13桁のシリアル番号が与えられる。(シリアル番号は箱に貼り付け) 測定後、マッチングされ出荷されている。NS社で測定されたペアの誤差は同じ測定条件でテストしても、数十%ほどずれていることが多い。しかし、この高精度選別ではペアの誤差は5%以内(測定条件による)に抑えることができている。
商品の電気的特性以外(他の機器へのダメージ、バルブの傾き、バルブの高さ、ロゴ欠け等)は保証対象外。

What is ZenPlus?
ZenPlus is an online shopping platform connecting Japan with the rest of the world. We're part of the ZenGroup, Inc. umbrella in Osaka, Japan.

Are items authentic?
Our sellers' agreement fully compels all stores to list only authentic items. We help you buy exclusive and authentic items from Japan, online!

Do you ship to my country?
We ship to all countries where Japan Post air freight services and international couriers currently operate. We don't use surface mail.

How long does shipping take?
Domestic shipments generally reach our warehouse in a few days, but may in certain specific cases take a week or more. International shipments can take anywhere from several days to several weeks to reach you after leaving our warehouse, depending on if you choose Standard or Express shipping.
Please contact our support team from the Questions section on your account page if you have any questions about the timing of your parcel.

How much is shipping?
Shipping costs depend on the size, weight, and destination of your parcel. We provide shipping costs for your order at checkout.

Will I be charged a customs (import) fee?
It depends on your country and its customs regulations. Our service does not cover duties and import taxes — in general, if the customs office in your country applies charges to your package, you are required to pay them.
