サンスイ AU-α907DR 中古品を整備したものです。

入手時にはプロテクトは解除されるものの、正常には音が出ませんでした。
ボリュームのガリ、SW・リレーの接触不良などが原因でした。

外観には年数なりの傷や汚れがありますが、リアパネルのサビを除けば比較的良好です。
写真を見て判断してください。

入手時にタバコ臭を感じましたが、内外をセスキで丁寧にふき取りましたので、かなり改善はしました。
しかし完全には除去できませんでしたので、タバコの臭いに神経質な方にはお勧めしません。


【整備内容】
・ スピーカー・ヘッドフォンリレー  3個 分解し接点磨き・接点復活剤塗布
・ すべてのボリュームはアルコール+超音波洗浄、その後接点復活剤塗布、ガリなし
・ PushSW(8個)はアルコール+超音波洗浄その後接点復活剤塗布、ON抵抗を確認。
・ スライドSW(5個)は基板から取り外し、分解清掃、接点磨きおよび接点グリスを処置
・ Power AMP部の終段バイアス電流、出力DC Offset、出力DC電位調整を実施。
・ Pre AMPのDC Offset調整を実施。
・ リアパネルの入出力端子磨きを実施


【確認内容】
・打診(基板を叩いて機能不良やノイズ発生がないことを確認)を実施
・ CD、Line、TUNER、Tape1,2,3、NORMAL1,2、BALANCED 入力で音出し確認。
   NORMAL, BALANCED入力, INTEGRATEDモード SOURCE DIRECTで 20Hzから120KHz までの周波数特性がフラットであることを確認
・ Loudness、Subsonic ONで周波数特性がそれなりに変化することを確認
・ PHONO入力は逆RIAAフィルターを通して周波数特性を確認し、 MM/MCともRIAAカーブにほぼ沿っていることを確認。
 (MC入力のみ 低域 30Hz で-3dB)
・ 周波数スイープ入力で、SP端子に8Ω+8Ωのダミー抵抗を接続し、出力 21W+21Wで数時間エージングし異常がないことを確認。
・ Processor機能はチェック済
・ ダンピングファクターをON/OFF法で測定。 スピーカーA側 L/R = 127/128 B側 L/R = 133/125  で問題なし 

整備後の周波数特性は写真-10 を参照してください。
現在のところすべての機能は正常です。

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.
