KENWOOD L-A1を出品させて頂きます。

"L"はKENWOODの研究所で開発された商品であり、当時の売価\280,000に対して赤字ではないかと思うほどの材料、機能を持ち兼ねているアンプとなります。KENWOODのLシリーズは実験的な高級機が揃っていますが、L-A1は同社にとって高級アンプ最終モデルとなりました。

【特徴】
・厚さ5mmのアルミ隊から削り出しで製作したフロントパネルを採用しています。
・Super C4(スーパー・コンスタント・カレント・カスケード・サーキット)は、初段増幅部に採用された技術です。同相成分ノイズの発生を防ぐため、初段電圧増幅部を独立させ、ボリュームアッテネーターの直後に配置することで、信号成分のみの差動増幅動作を実現しています。これにより、高い同相成分除去率(CMRR)と安定した素子内部の動作状態を保ち、信号の混変調やS/N比の劣化を抑えました。
・クアドライブ・マルチプル・ファイナル・ステージは、最終段を駆動するドライバー段を強化した技術です。従来のアンプでは、複数のファイナルトランジスタに対してドライバー段がシングル接続でしたが、L-A1では各ファイナルトランジスタごとに専用のドライバーを独立して持たせています。これにより、各ドライバーの負担が分散され、駆動力が向上し、低インピーダンスのスピーカーに対しても高い駆動能力を発揮します。また、大電力を扱うファイナル段と小電力を扱うドライバー段の基板をヒートシンクの表裏に分離して配置することで、放熱効果を高めています。プリドライバー段とドライバー段は純A級動作で、スイッチング歪の発生を抑え、熱的に安定した動作を実現しています。
・完全シールド型超低インピーダンス抵抗体回転式ボリューム:摺動子が固定され、円盤状の抵抗体が回転することで接点の数を減らし、高音質化を図っています。インピーダンスは通常の1/100にあたる1kΩで、熱雑音を1/10に抑えています。
高硬度のガラスエポキシ基板を採用しています。(基板の誘電率が低いため音質重視の基板回路設計となっています。)

【補足】
この時代のスピーカー端子は樹脂製で破損し易くプラグ端子も使えない為、金属性+プラグが使用できる端子に交換しています。
半田に関しては、1990年代当時の半田を使用しています。計測機で測定していませんが音質には変化がないと思っています。
左右WOODパネル後方TOPに傷など御座います。写真を確認ください。
その他とても綺麗な個体になります。

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.

※ Note: Photos provided to sellers should not contain any foreign-related information.
