ラックスキットA3700Ⅱ中古をフルレストアしました。

アンプは音質の優れたパーツを厳選して組み上げたため、演奏者の息づかいやライブ演奏のバックグラウンドノイズなど細部の再現性も極めて優れたもので、豊かな低音を伴い、従来のLUXアンプと一線を画したマッキントッシュMC275に勝るとも劣らないサウンドに仕上がっています。
演奏の広がりや奥行き感の再現性に優れ、ヴォーカルの再現性に優れていてあたかも目の前で歌っているように聞こえます。
また、ライブ演奏の拍手を聴いてみて下さい。出来の悪いアンプですと刺激的な音になりますがこのアンプではクリアーで柔らかくまるでその場にいるような感覚が得られます。
シャープでクリアなのに柔らかい、旧来の真空管アンプとは一線を画した音質に仕上がっています。

部品、配線を全て外してクリーニング後、新たに組み直しました。RCA入力端子には工作精度の高いモガミネグレックスを使用。スピーカー端子はバナナプラグ対応。
出力管ソケットはLUX製を再生して使用。MT管ソケットは金メッキピンセラミック製新品。ボリュームは導電性プラスチックを使用した信頼性の高い製品を採用しています。組み立てには基本的にウルトラスリムヘッドビスを使用してスマートな外観になるように気をつけています。
更に、出力管交換時のバイアス調整をアンプをひっくり返したり、裏蓋を外すことなしに出来るよう測定端子と調整ボリュームをシャーシー上面に配置していますので球転がしが楽に出来ます。

配線材は高品質高音質のBELDENフックアップワイヤーを使用。カップリングコンデンサーは音の良いWIMAのポリプロピレンフィルムコンデンサーの中でも最高級品である金属箔電極使用のFKP1を使用しています。バイパスコンデンサーにはやはり音の良さで定評のあるVishayのフィルムコンデンサーを採用。抵抗はVishay Daleの金属皮膜抵抗を使用しています。
電源のブロックコンデンサーは容量の測定値が定格以上でESR値も正常なので交換の必要無く、そのまま使用しています。
出力管はPSVAN KT88新品を搭載しています。非常に優れた球でGEC KT88 GOLD LIONに引けを取らないサウンドを聴かせてくれます。

初段にはGE 5670W 5STAR、NOS(New Old Stock)を使用。
この球はマイクロフォニックノイズが低く、並外れて長寿命な製品で当時の販売価格は非常に高価でした。
また、製造されたものの大半を米国陸軍と海軍が備蓄したので一般には殆ど流通しなかったことに加え備蓄が放出された後も12AU7や6AQ8等とピン配列が違うこともあり現在は手頃な値段で入手できるコスパ抜群の優れものです。

ドライバー管は信頼性の高い東芝製の中でも通測用高信頼規格の5687WA、NOSを使用しています。

アンプを組み上げてから1週間以上作動して異常が無いことを確認して最終調整しています。

メンテナンス用に回路図、出力管交換時の調整方法の図面を同梱します。

なお、レストア品ですから少々の傷、錆等がありますから写真でご確認下さい。また、神経質な方、完璧を求める方は入札をご遠慮下さい。

International Shipping Methods
Singapore Package Import: Customs and Tax Policies
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-holdings.com 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.
