【ラインアンプ】
お気楽オーディオキット資料館のA12タイプ基板を使用したLH0032等価回路のラインアンプです(参考URL: http://www.easyaudiokit.com/bekkan/manual/RenewDiscreteAmpManaual.pdf 及び http://www.easyaudiokit.com/bekkan/renew-discre/renew-discre.html)。
ライン入力3系統、出力1系統、およびSub Woofer出力1系統です。Sub Woofer出力は、オペアンプを使用たL/Rミックス回路です。
電源には、三端子レギュレータに加えてTPS7A4700を使用した秋月電子の超ローノイズ安定化電源を使用しています(https://akizukidenshi.com/catalog/g/gK-06194/)。
ローノイズ電源で、ケースの大きさに余裕がありますので、イコライザー回路の組み込みも可能です。
ケースは8mm角の真鍮角材をフレームとした自作品です。大きな傷はありませんが、フロントパネルにこすり跡があります。頑丈に作ってありますが、自作品のため、メーカー品ほど美しくはありませんのでご承知おきください。

【オールFET DCパワーアンプ】
金田式アンプを研究されているkontonさんの記事を参考に作製したオールFET DCパワーアンプです(参考URL:http://www7b.biglobe.ne.jp/~konton/BATTERY%20DRIVE%20MOS-FET%20POWER%20AMP%202011.htm)。
kontonさんが発表された回路では、初段のFETに2SK30×2を使われていますが、本品ではソリトロンの2N3954Aを使用しています。電源トランスはフニックス製Rコアです。プロテクタ(整流・DC検出・ミュート回路)は、スイッチサイエンス製整流・プロテクタ基板「PRT-02」を使用しています。さらにLM350とLT1033を使用したL・R独立安定化電源となっております。
ラインアンプ用のACサービスコンセントが付いていますが、2回路電源スイッチを使用しており、サービスコンセントはフューズを通っていません。ケースはタカチ製です。中古ですが、2SK134×2と2SJ49×2(日立)を付属します。
また、参考資料として、インチ基板を使用した配線パタン図、スイッチサイエンスプロテクタPRT-02のマニュアル、プロテクタPRT-02回路図、基板図、接続図のpdfファイルを書き込んだCD-ROMを付属します。

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.
