マランツ#7タイプ 自作 プリアンプ (真空管12AX7 3本は付属しません) をシリーズ2台目を出品いたします。
私が過去から製作して来て、一番多く手掛けて来たマランツ7のイコライザーコピーしたアンプになります。イコライザー回路は、部品配置なども考えオリジナルに近づくように製作しました。ライン部はWE396Aを念頭に無帰還のLINE出力トランス(600Ω)出しの回路になります。球の構成は4球(12AX7 3本 2C51WE396A他可) 1本)になっています。重要:12AX73本は付属しません、ご自分で好きなものを使ってください。2C51はロシア製高信頼管の互換球6H3n-EBが付属します。
シャーシーはオリジナルの特注品になります、1.6tスチール製でW420XD260XH120のサイズです。塗装はガンメタリックのハンマートーンでフロントはシルク印刷で業者依頼の特注になります。リアパネルの文字はインレタになっています。
本機のLINEの真空管は2C51の他にWE396Aなどの互換球が多くあるので球転がしで楽しんだり、また出力トランスはTOEI20K600Ωを使っていますが、スペースがあるので技術のある方は入れ替えてUTC,などの高級品に変えてみるのも良いかと思います。
電源はノイズの少ないRコアトランスを使用、倍電圧回路構成で整流Diはシリコンカーバイトを使っています。音出しチェックには松下の12AX7で行っています。
使用している部品はビンテージ品で抵抗はA&Bソリッド、カマヤ、金属皮膜のDALE等を使用、カップリングはASCTRWCDEEQ素子コンデンサーはスチロールを使用しております。信号回路配線材はWE22G単線をメインに使用、シールド線はモガミ2944等を使用です。ボリュームはトーコスRV24-250K-Aを使用しています。パイロットランプにはUSAの古いものを使っています、色は赤で均等に発色しています。
振動吸収目的で真空管、部品基板はダンパーゴムで浮かせてあります、フォノジャックと真空管の間はシールド線に変えてイギリス製単線を使っています綺麗な高域が期待できます。ハムノイズは私のアルテックA5で通常リスニングポジション5m位でVR9時から12時で気になりません。(個人判断)個人評価になりますが、音質は過去にCRLCR、マッキン型、クオード型等いろいろと製作しましたがNF型のマランツ型かマッキン型が私には一番しっくり来ます。
ここまで、長文をお読みいただきありがとうございます。発送はゆうパック着払いでお送りいたします。音が出ない以外は基本的にNC,NRでお願いいたします。お断り:一部使いまわし画像を使用しています。

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.
