【概要】
★新品★ オペアンプ LH0032専用 デュアルオペアンプ化基板セット
 
シングルオペアンプLH0032 2個をデュアルオペアンプのピンレイアウトに変換する基板です。
 
私は、基本オペアンプは必ず正規代理店より購入します。しかし廃盤品は既に正規代理店では販売中止のケースが大半です。
本物のオペアンプを所有していれば、オシロスコープで波形を比較し真贋が確かめられるので、どうしても欲しいオペアンプなら
正規代理店以外からも購入することはありますが、偽物の流通が多いので手を出すことは非常に少ないです。
 ただ、正規代理店から購入したと思われるパッケージで販売している人がいたため、調べてみるとLH0032がとても音質の良いオペアンプである
ことが分かり購入してみました。しかし、変換基板がない事には、オペアンプを購入しても意味がありません。
その為、海外より取り寄せしてみました。
 
変換基板1枚、ヘッダーピン2個、チップコンデンサー2個のセットです。
 
※半田処理はコツがありますが、チップコンデンサーの半田処理も含めそこまで難しいというものではありません。
ただ基板の穴の間隔が一部狭いので、半田の付け過ぎでショートしないようご注意ください。
また基板に番号等が付されているので分かるとは思いますが、チップコンデンサーが付く方が下になります。
 
幾つか組立てみてわかったことは、半田処理が悪いと左右の音量バランスが崩れたり、ノイズが発生しやすいようです。
しかし、きちんと組みあがった時は、音質がとても良いです。もし、オペアンプを触ってノイズが出たりする場合、半田処理が悪い可能性があります。
私が試した環境は、LUXMANのデジタルアンプ(LXA―OT4・・・ONTOMO SHOPで販売中)でのオペアンプ交換ですが、
低ノイズ電源で試したところ、上級クラスの音質に化けました。非常にお勧めです。
 
ネット上の記事にもあるように、発熱がすごいです。ヒートシンクを取り付けた方が良いと思います。
 
ちなみにLH0032は、プレミアがついていますが、一部の正規代理店や国内の電子部品を取り扱っているところでも、まだ少し在庫が残っているようです。
 
【取引条件等】
 新品で購入したものですが、基本ノークレーム・ノーリターンです。
保証を求めるのであれば、専門ショップで購入してください。
当方はショップではないので落札後挨拶文を送ったりすることはないです。落札者側から取引ナビに従って取引を進めてください。
評価につきまして当方に評価が入った場合のみ評価を返しておりますが、取引ナビのルールに従わない(受取連絡をしない)落札者は評価に反映させる可能性が高いです。

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.
