NECがオーディオ事業最後のプリメインアンプとして1989年末に発売したA-10X、当時の定価は175,000円
当時としては画期的なアイデアが盛り込まれつつトーンコントロールなどもなくシンプルイズベストを追求したアンプだと思います。

  1)ツインモノコンストラクション<、L/Rチャンネルはトランスやフィルターコンデンサー、電圧増幅段の基板に至るまで完全に独立させた左右対称構成。
  2)電源部にはA-10シリーズ伝統のリザーブ電源を採用、安定した電流供給能力と強力なダイナミックレンジを確保。
  3)平滑コンデンサーには大容量かつローインピーダンス・ハイスピードのカスタムコンデンサーを採用しており、コンベンショナル電源15,000μFx4、リザーブ電源15,000μFx4のトータル120,000μF構成。
  4)スピーカー出力の保護回路には新開発のバイアスショート型保護回路を採用。これによりプロテクションリレー方式でスピーカー出力に直列にリレーが入る事による出力インピーダンスの上昇や歪の付加、接触不良などで音楽信号に与える悪影響を排除。
  5)入力セレクターとして密閉型金メッキツイン・クロスバー接点リレーをリアパネルの入力端子近くに設置、接触不良、ガリなどの排除。
  6)端子には金メッキを施した高級削り出し高剛性RCAピンジャックを採用、接点を強固にすると同時に入力ブロック全体を非磁性体化。
などなど、豪華筐体も含め販売コスト以上にお金をかけていると思います。

特に4)5)は、いわゆるクレームの温床である切替スイッチ・リレー接点劣化接触不良による信号経路の高信頼性化につながっていると思います。
入力切替用のリレーは何個か分解調査しても接触抵抗の増加も見られず接触信頼性は高いと思います。
搭載リレーは精密電子回路用密閉型ツインクロスバー金メッキリレーです、オーディオアンプのメーカーでは一般リレー単接点の搭載がほとんどです。

唯一、本機種はボリュームの経年劣化でガリが多く発生するものが見受けられる様です。
また、時代を反映し本機種はPHONO回路は搭載しておりませんのでご注意下さい。

【状態】
 ・小傷、すれ、など僅かにありますがダメージのあるものはないと思います。概ね綺麗ではと思います、外観は主観ですのでご了承下さい。
 ・内部は使用感少なくきれいな個体です。
 ・全ての入出力などの確認部分は正常動作品です。
  (測定器チェックではなくあくまでも聴感上です)
 ・禁煙環境品です。
《メンテナンス実施内容》
 ・入力RCAターミナルクリーニング。
 ・保護リレー分解クリーニング→写真10枚目、B接点側接触抵抗、ほぼゼロΩにしています。
 ・ボリューム分解クリーニング
 ・ゼロバランス電圧確認

 ・半田付けチェック、特に修正ポイントはありません
【付属品】
 ・特にありません
【発送】

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:

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.
