  1. Plug-in electrical appliances are only shipped by air (shipping by sea requires commodity inspection)
※カテゴリーが違いますが「真空管アンプ」とセットになる機器なので、こちらのカテゴリーに出品させて頂きました。
 
今までDACと真空管プリの間に入れて聴いていましたがトランス内蔵のプリを導入予定ですので、こちらの方を出品いたします。
 
動作は今まで聴いていましたので問題はありません。電源が必要無いので滅多に壊れるような物でもありません。
 
出品に辺り、前・後面のネジに錆が若干出ていましたので新品のネジに交換しました。また、内部も含めて全体を清掃しています。
 
外観は画像のとおり、経年品としては綺麗な方だと思います。
 
主な仕様は下記のとおりですが、本ライントランスは前期型でOUTPUTインピーダンスがA(200Ω~500Ω)B(OVER 500Ω)C(UNDER 200Ω)と選べるようになっています。コスト削減かどうかは分かりませんが後期型はOUTINのみとなっており、インピーダンスが選べません。そう言う意味では前期型の方が優れていると思います。
 
仕様などは下記のとおりですが、故上杉氏はこんな事を言っていました。「トランスを通した方が、音が滑らかになります。12年ものウイスキーが21年もののウイスキーになったようなイメージです。これはトランスが不要超高域雑音信号をカットする役目を果たしてくれるからなのでしょう」と...
 
UESUGI CD特有のデジタルノイズを減衰する機能となりCDプレーヤーとプリアンプ間をライン接続します。
高性能なアイソレーション型ライントランス(受動部品)で構成され電源は必要としません。
1985
年~93年頃まで製造されており、約1000台程度市販化されています。
当時世界で初めてコモン・モード・ノイズを除去する機器として製品化された開発秘話を以下にて少しご紹介します
上杉研究所ではディジタル・ソースには素質が優れているがゆえに、こういった問題点は再生側にあるのではないかと考え、その解決に真剣に取り組んでいました。そして、上杉研究所のアンプに関するノウハウを駆使して、2年の歳月を費やして研究した結果、ついにそういった問題点の原因の発見と解決法に、世界で初めて成功しました、さきほど述べましたディジタル・ソースの再生ににおける音質的欠点は、デジタル機器から発生するコモン・モード・ノイズが原因である事をつきとめたのです。
(
ディジタル・プレイヤー・システムの欠点を追放したい UBROS-6 上杉佳郎 記)
製造:1985年(当時販売価格88000円)」ここまで。

どなたか必要な方、入札願います。
 
ゆうパック60サイズ(東京まで760)の予定です。
 
ご入札される方は自己紹介欄とマイナスの評価は必ず見てください。マイナスの評価はそれなりの理由があるものが殆どです。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
