SONY SA-IF70+別売りのインプットアダプターです。

RCA端子とかじゃなく、アンプのSP端子に直接繋げられるのがちょっと珍しい
SONYのアンプ内蔵 赤外線ワイヤレス パワード ステレオスピーカーです。
インプットアダプター IAD-IF70とトランスミッターのEMT-70、パワードスピーカーのSA-IF70S L/Rのセット。

SONYのAVアンプTA-V909/TA-V606の場合は、インプットアダプター無しで、
直接赤外線トランスミッターをつけれる端子があるようですが
これの最大特徴は、どんなアンプでもスピーカー端子があれば汎用で使える
本来別売りのインプットアダプターIAD-IF70でしょう。

20数年前に5.1chのリアで使用していました。
前から後ろまでの長い取り回しの配線不要なので便利でした。
その後、転勤もあり、実家倉庫に輸送・保管。
1年ほど前に発掘、動くけど不具合があり、サービスマニュアルの部品表頼りに
修理しようと保管していましたが・・・・、時間が無く手が回らないので出品です。

SA-IF70
アンプ内蔵・1ウェイ・1スピーカー・バスレフ方式・ブックシェルフ型

■外観
・ちょっと全体的にくたびれています
R側スピーカー上部ネットに敗れがあります(画像2参照
・インプットアダプターのフロントパネルのシール(薄い樹脂に印刷品)が剥がれて無くなっています。
  本来書かれていたのは、左から電源、INPUT-A、LEVEL です。
・大きな割れ、はありません。

■動作状況
適当なAMPのスピーカー端子に送信機を接続、
送信機よりスピーカー.を数mほど離して動作させたところ
(なお、電源スイッチがあるのは、送信機フロントのみです)
送信LEDは全て点灯(画像1参照、一応、両方のスピーカーから音は出ました。


不具合点として
・R側スピーカーのみ、コンセントを挿しても電源ランプが点きません。(音は出る
・L/R両方のスピーカーから音は出ますが、使っていた頃に比べて、なんか音量が小さいです。
・L/R両方のスピーカーから音は出ますが、周期的に音量が大きくなったり小さくなったりします。

以上によりジャンク扱いとさせていただきます。

とりあえずは音が出ているので、予想としてはスピーカユニット側のアンプか赤外線受信回路の
抵抗かコンデンサの経年劣化による不調と思われます。
なお、劣化等で、このまま無理やり通電続けると、不良箇所は増えたりする可能性もありますのでご注意下さい。

幸い、海外にも出荷されていたのか、英語ですがサービスマニュアルがあり、無料でダウンロードできます。
https://www.manualslib.com/manual/2517708/Sony-Sa-If70.html#product-SA-IF70

サービスマニュアルに、基盤の実体配線図、及び部品表がありますので修理も可能と思います。

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.

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.
