LUXMAN(ラックスマン) SQ-507X プリメインアンプ 2SA649 2SD218 使用 整備済み完動品です。入手した動作不安定品をほぼオーバーホールに近い形で整備したものです。1971年の発売で、当時のラックスマン プリメインアンプのフラッグシップ機です。出力トランジスタは、今では入手困難品になったメタルキャン銘石の2SA649 2SD218をシングル使用し50W×2の出力です。このトランジスタは音質を高く評価されて初期の金田アンプで重用されました。ドライブ部も今では貴重な2SA606 2SC959を使用しています。整備にあたり小信号トランジスタはXA495を除いて全交換しました。電解コンデンサは電源部のブロックコンデンサを除いたアルミコンデンサ全てをニチコンのオーディオ用Fine Goldに交換しました。スイッチ類とボリュームはCAIGで洗浄を実施しています。DCバランスとアイドリング電流調整用の半固定抵抗を全交換し、ヒューズ5本も全交換しています。この時代のアンプは手作業で製作されていて、各部品や素子は基板に折り曲げハンダ付けの上、ハンダ盛りも厚く非常に丁寧な作業が伺えます。SP端子はプラスチック部の破損があったためバナナプラグ対応の金属ネジ式に交換しました。電源ケーブルは今となっては珍しい本体2P型インレットの着脱式でしたが、これを本体3P型に交換しました。アース端子は未配線です。新品汎用ACケーブルをお付けしますが好みで高性能ケーブルに交換されてください。本体機能としては、入力がMMPHONO 12AUX 1235系統で他にTAPE2系統あります。PHONO1は負荷抵抗を3050100KΩの3段切り替えで、AUX1は入力レベル調整付きです。トーンコントロールは、BASSTREBLEそれぞれ周波数3段階切り替え仕様でDEFEAT位置も装備されています。他にローブースト、ローカット、ハイカットが装備されています。回路はこの後長期に亘り主流となる全段直結コンプリメンタリー型です。保護回路は出力トランジスタのヒューズのみです。外観についてはリアパネルには薄く錆が浮いてきていますがプリント文字消えが嫌なのでクリアを塗っただけでそのままにしています。音質は終段の2SA649 2SD218の働きもあって極めて高音質です。非常にクリアな音質に加えて音場も広大で現代機種と比べても遜色ないと思います。元々なのかボリュームにギャングエラーがありボリュームを絞り切っても右チャンネルからわずかに音が出ますのでご了解ください。あまり使用しないかとは思いますがアッテネータのON/OFF時にノイズが出ます。ヴィンテージ機としては概ね美品ですが、完全美品をお探しの方はご遠慮ください。出品内容は本体とACコードです。ゆうパックおてがる版120サイズでの発送を予定しています。到着時に動作しない場合を除きノークレーム、ノーリターンでお願いします。

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.
