ご覧いただきありがとうございます。

有名なMarantz7T を何とか自作すべく基板を作ってみました。 できるだけオリジナルに近いものにしましたつもりです(オリジナルの部品等は入手不可能に近いので)回路乗数、電圧などは近づけるべく設定にしております。


Marantz 7Tサービスマニュアル(Marantz)、世界の名器に挑戦(CQ出版社) マランツ7T(古家秀 編)、ラジオ技術 1988年、2月・9月号(石井義治 編)を参考にしてまとめた基板になります。
イコライザー・アンプ基板とフラット(コントロール)アンプ基板の2枚組となります。
L・R(ステレオ)です。

世界の名器に挑戦 掲載記事内容より抜粋です
菅野沖彦  マランツ7T+マランツ#15「ふわっと拡がって前へ迫る音の波、まさに日頃使い慣れっているMarantzアンプの持ち味通じるもの・・・音像の再現が実によく・・・音像の再現実によく似ている・・・」

* 再現性は高いです( デジタル・テスター一丁で組立できます・・・抵抗値、コンデンサ、TRの良否確認用などです)
* 基板のトランジスターは正面(平らな印字面から見てECB配列にしております)。
* 回路図、簡単な組み立て説明書をつけております。
* ラ技に掲載の回路図に間違いがあるので訂正しています。

* DVDデーター 組立資料、データーをDVDデーターでお渡しします。
  (元資料によっては経年により変色・退色などによりプリンター印刷では、文字が読み難い事もありDVD盤でお渡ししま  す、何せ、50年以上経過しているのもあるもあるのでご理解を  m(__)m )

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.
