御覧頂きありがとうございます。
説明をよくお読み頂きご納得の上、入札をお願いします。

テクニクス(Tecnnics)製 プリメインアンプ SU-2300 動作品です。
1976年頃の製品で、当時の同社のプリメインアンプとして、ローエンド機種となります。
詳しくは下記を参照してください。
https://audio-heritage.jp/TECHNICS/amp/su-2300.html(オーディオの足跡)

この機種のことをいろいろ調べてみたくて最近入手したのですが、役目を終えたので出品します。
本製品の定格出力は、10w+10wですが、本製品のパワーアンプ部に採用されている STK043
というワンチップIC単体の定格出力は 20w+20wとなっています。
他の部品のコストを抑えるために、あえて本機は定格出力を10w+10wに下げたと思われます。
1976年当時だと多少歪が増えようが 定格出力どころかミュージックパワー(瞬時的な出力)で
30w+30wくらいの設計にしてカタログを飾るのが普通でした。
定格出力10w+10wというスペックは、結果的に低歪となる出力帯域を使う設計となるので、
音質的には良心的な製品だと云えます。
試しに、家にある最も低能率のスピーカーを接続して最大ボリュームで視聴してみましたが、
かなりの爆音に関わらず、歪はほとんど感じられませんでした。

動作状態ですが、以下全ての機能を動作確認済です。
・PHONO、TUNER、TAPE/AUX 各入力についてスピーカーおよびヘッドホン端子での音出し確認
・VOLUME、TONE CONTROL、BALANCE つまみの動作確認
・PLAYBACK端子への信号出力
バランスつまみセンター位置での左右の音量差は、ほぼありません。
ガリは若干出ることがありますが、気になるほどではありません。

外観については、全体的にキズや汚れ、またケースの錆などが見られます。
入手後、クリーナー等でいろいろ清掃して少し小奇麗にしましたが、「傷や汚れあり」です。
各画像で確認してください。

製造後、半世紀経過している製品ですので到着時に 電源が入らない/音が出ない 以外は
ノークレームをご了解いただける方のみ入札をお願いします。

商品内容は、SU-2300本体のみとなります。
(電源コードは、着脱不可です。)
発送は、ゆうパック 100サイズ となります。

落札者のご負担は落札価格+送料です。消費税はかかりません。
また個人出品のため、インボイスには対応いたしません。
当方、特に取引を急いではおりませんが、かんたん決済の期限はお守り頂けるようお願いします。
期限内にご決済頂けなかった場合は、お取引きを放棄したものと判断し「落札者都合でキャンセル」
させて頂きますので予めご承知おき下さい。

評価の悪い人の入札は、悪い評価の数、内容を当方で判断して 削除させて頂く場合があります。

自己紹介にも記載していますが、個別交渉による取引には応じておりません。

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.
