私の出品物をご覧頂き有難う御座います。
長らく病気療養しておりましたが幾分復調して来ました為、整備品の出品を再開させて頂きます。
発送はクロネコ又はゆうパック着払い140サイズを予定しております。
尚、昨今の燃料費の高騰で不在持ち戻りを防ぐために日時指定をお願いしておりますが、
指定頂けない方が増えています。
又、此方が催促するまでお取引を開始して頂けない、商品の受け取り連絡を頂けない方が多いです。
速やかなお取引をして頂けない方の入札はお断りさせて頂きますので予めご了承ください。
以下、商品の説明です。

ケンウッドが'84年頃に発売した¥79800クラスのスタンダードモデル、KA-990SDです。頂き物になります。
「しばらく保管して居る間に音が出なくなってしまった」との事でした。
原因は他愛も無い要因で「アダプター端子のショートピンプラグの挿し忘れ」によるものでした。
原因を説明しましたが「新しいアンプを購入したので構わない」、との事でした。
下記の基本的なメンテナンスを実施済です。

1、内部の分解清掃
2、カバー、底板、パネル及びツマミ類の分解洗浄
3、底面のメイン基板のほぼ全箇所及び各所の半田補修
4、各種ボリューム、スイッチ類の接点洗浄
5、リレー接点の清掃
6、外装仕上げ

以上のメンテナンスを実施済です。
ガリ、ポップノイズ等は有りませんが残念ながら1点、TONEに難が有ります。

BASS : 右チャンネルは変化しますが左チャンネルは変化しません。
TREBLE: 左チャンネルは変化しますが右チャンネルは変化しません。

この点に難が有りますので現状渡しとさせて頂きます。
外装は小さな傷、僅かな文字消え等は散見されますが年式を考慮しても美品の部類だと思います。
付属品はスピーカーケーブル2本、ピンケーブル1本、社外品のショートピンプラグ2本
(アダプター端子に装着済・アダプター端子を使わない場合にはプラグを抜かないで下さい。音が出なくなります。)
以上になります。
尚、全ての機能・端子に関してはチェックしておりません。ご了承下さい。
(フォノ入力等・レコードプレーヤーを持って居ない為。)

到着時に電源が入らない、音が出ない等の不具合には対応させて頂きますが基本的には現状渡し返品不可にてお願い致します。

(2026年 5月 3日 0時 28分 追加)
只今、同じケンウッド(トリオ)のKA-8300コンデンサー交換チューンナップ品の出品準備をしております。
ほぼ同じ価格帯の製品ですが音のキャラクターがまるで違います。
(何方が良いとかでは無くて好みの問題ですが。)
KA-8300は'78年発売で¥78000ですが重量は990SDよりも重い13.5kg、990SDのパワーアンプIC構成に対してトランジスタ構成になって居ますが、出力は990SDよりも低い様に感じます。
引き続きご検討下さい。

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.

※ Note: Photos provided to sellers should not contain any foreign-related information.
