【商品説明】
・高度な整備品 SONY ソニー TA-F6B  ステレオプリメインアンプ
・HEAD AMP(MC)入力にオルトフォンSPU GEで音出ししました。その他各入出力動作確認
・パルス定電圧電源搭載なので同出力機と比較して軽いです。
・パルス定電圧電源を点検しましたが、劣化したコンデンサはありませんでした。


【外観】
・前面パネルは綺麗ですが、パネル上部角に小傷あります。
・天板、左右側面は小傷、部分塗装禿ありましたのでプリントを除き塗装しました。

【整備詳細】
・メーター照明点灯回路について(パルス定電圧電源電圧(+49V)を抵抗直列、ラッシュ解除リレー直列、メーターランプ並列を直列接続(-GND)した回路です。ここで問題になるのが、メーターランプが切れたらどうなるかです。例えば、左側が先に切れたとすると右側のメーターランプには過電流が流れ、ラッシュ解除リレーには過電圧が架かり発熱し右側のメーターランプは明るくなって短期間で切れます。切れると回路は遮断されますからラッシュ解除リレーは解放されラッシュ防止回路(抵抗2.2Ω直列109℃温度ヒューズ直列2.2Ω直列接続)抵抗が発熱します。パワーを上げると温度がさらに上昇して温度ヒューズが切れます。切れるとパルス定電圧電源に電圧(コンセント交流電圧を直接ダイオードブリッジ整流)供給されないのでアンプは電源が入らない状態になります。このような症状にならないためにメーターランプをLED照明に,メーターランプを等価抵抗にしてラッシュ解除リレーを動作させています
・メーターランプLED照明電源はパルス定電圧電源49Vをトランジスタとツェナーダイオードで12V定電圧電源
・メインアンプ足の黒いトランジスタ取替
・ラッシュ解除リレー接点腐食接触不良、カバー熱変形、開放型を密閉型に取替(リレー取替は必須になります。取替ない整備品は要注意です。)
・パルス定電圧電源ラッシュ解除リレーに並列のタイミングコンデンサー熱劣化のため取替
・出力リレータイミングコンデンサ接着剤で足腐食取替
・メインアンプIC±電源用コンデンサ熱劣化左右4個取替
・バイアス調整用半固定抵抗を多回転半固定抵抗に取替調整(半固定抵抗取替は必須になります。取替ない整備品は要注意です。)
・DCバランス調整用半固定抵抗を多回転半固定抵抗に取替調整
・メインボリュームを基板から取り外し接点洗浄剤で清掃
・トーンアンプIC右側から雑音ありICピン清掃しましたが雑音出るので取替。左側はICピン清掃
・出力リレー接点洗浄剤で清掃
・各ボリューム、各スイッチ接点洗浄剤で清掃
・メーター出力1W確認

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.
