サンスイのブラックフェイス1号機の最高級真空管プリメインアンプ AU-111作動品です。
もちろん出力管6L6GC他 真空管類もオリジナルです。今でも綺麗な音を奏でます。

難点としては入力端子の下側が本機の台入れの際のスレで削れが見られますが接触には問題なし。またツマミの中に一部若干ガタが見受けられます。底面パネルに錆あり。

そろそろ終活の為コレクション整理で泣く泣く格安で出品します。

出来ればデリケートな機器なので取りに来られて作動確認頂ける方にお譲りしたいです。
基本ビンテージ品の為ノークレームノーリターンでお願いします。

以下本機の仕様です。
ちょうど真空管とトランジスタが入れ替わる時期に発売され、サンスイ最後にして最高峰の真空管プリメインアンプとして発売されました。 
出力管には6L6GCを採用しており、AB1PP固定バイアス方式で動作させています。
また、多重負帰還回路の構成で全帯域にわたって平坦な特性を得ています。
 トランスには超広帯域型のアウトプットと、定損が少なくレギュレーションの優れたパワートランスを採用してます。これらのトランスは全て永久保障がされてました。
 コントロールアンプ部にはカソードフォロアーを含めて4段構成の増幅回路を使用してます。
また、全てをNFアンプで構成しノイズを抑えています。
 プリアンプ部とメインアンプ部がそれぞれ独立して使用できるように設計されています。
 
低域2段、高域2段の合計4段に上昇点、下降点が切替えられるトーンコントロールを採用しています。
高域低域それぞれを独立して自由にデフィート(トーン回路キャンセル装置)も可能です。 
サンスイの入力トランス(A-603A-604)との組み合わせで、低出力のMC型カートリッジでも使用可能です。
 ヘッドアンプは新型シリコントランジスタ(マイクロ・セップ)も採用しています。
 中間アンプの初段は入力インピーダンスが高く、出力インピーダンスの低いカソードフォロアー回路を採用しています。
2種類のテープイコライザー。 
カソードフォロワーによる低インピーダンステープ録音出力端子。
 CRフィードバック方式のロー・ハイフィルター。 
ラウドネスコントロール。 
全帯域用と3D方式用の灰・カットの2種類のセンター出力端子。
 低音域の歯切れを良くするプレゼンスコントロール。
 テープモニター、位相切換え、サブボリューム、ヘッドホン端子などのアクセサリーを搭載してます。

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.
