Notes
  1. Plug-in electrical appliances are only shipped by air (shipping by sea requires commodity inspection)
仕事仲間から譲ってもらった器械です。

「長年、オーディオ機器の開発で音の基準器として愛用してきた」との話でした。
(実際に今聴いても、「すこぶるレベルの高い音!」と感じられます)
確かに、今の機体の様子からその戦歴がうかがえます。
「プラスチックケースに塗装仕上げ」の為、電源SWは塗装が剥げてしまっています。
また、ハンダ鏝を当てて溶かしてしまった箇所も見受けられます。
一番問題なのはボリュームのスライダーです。
「プラスチックのレバーが折れて、ピンセットのような工具で動かしていた」とのことですが流石に使いにくいので折れたレバーに収縮チューブを被せて接着剤(スーパーXG)で固めました。レバーの動かし方に注意すれば結構長く使える?と期待しています。
汚れたスイッチトップには市販の化粧フィルム等を貼るだけでもイメージはガラッと変ると思います。
(自分でグレー等で印刷フィルムを作ってもよいかと思います)

信号系は各入出力問題ありませんが、パネルの入力セレクト表示でPHONOだけが点灯しない不具合があります。
ただ、表示が無ければPHONOと判断出来るので使用上、困ることは無さそうです。
この安っぽいプラスチックケースに関しては色々クレームが付いたようですが、アルマイト等では音が全く死んでしまうので当時の技術ではプラスチック以外の選択肢は無かったようです。

最近まで時々使われていた器械だけに、各電気的特性は優秀でした。
以下、実測値ですがMC入力も一般的な出力の製品なら充分なS/Nが確保できます。

入力換算ノイズ---
◎MC入力 Lch  0.25mV(A)  -151.4dBV
        Rch  0.23mV(A)  -152.1dBV
◎MM入力   Lch 25μV(A)    -143.4dBV
         Rch 24μV(A)   -143.8dBV
(RIAA偏差は両ch共0.2dB以内)

歪み率---
◎TUNER(AUX) 入力 Lch 0.00019%(1kHz 3Vout時)  
               Rch 0.00021%
◎MM入力  Lch  0.00076% 1kHz 7Vout時)   
             Rch  0.00075%

仕様:
サイズ: 幅 44cm×奥行き 38cm×高さ 7.5cm(足を含む)
重量: 4.5kg
定格電力: 38W

実は、このアンプを購入した際、強化電源ユニットL-08CPSも勧められて一緒に購入したそうですが、「色々移動して使うこともあって、結局この電源ユニットを使うことは無かった」との話でした。(接続の為の「工事」もされていません)
今回、この電源ユニットも渡されましたが取説等の資料が全く無いので、こちらで解析して今回一緒に出品することにしました。
(非常に強力な電源トランスが勿体ない、ということです)
追って別出品の予定ですので参考にしてください。
(接続用のコネクターは今も販売されていますので、アンプに詳しい方なら電源とセットで使いこなすことも可能ですが、このアンプ単体でも相当なレベルの音がしますので単体使用もお勧めです。アンプの回路図はHifiエンジン等で入手出来ますが鮮明な物は入手が難しそうです)



(2026年 7月 29日 13時 06分 追加)
本機は全スイッチ、ボリュームをメンテ済みでガリは有りません。

ついでに今は珍しくなったラウドネス調整に関して説明しておきます。
トーンコントロールとは違ってボリュームを絞った時のみ働く機能です。
ボリュームを絞ると特に低域の量感が無くなるのでボリュームに合わせて低域を増強します。
(本機の場合は高域を増強する機能はありません)

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.
