真空管ステレオ・パワーアンプ自作です

東芝6G-B8を出力管に採用しISO U-405出力トランスにてプッシュプル動作させたものです

初段6AU6 次段6C4をPK分割で位相反転させているのでALTEC型でしょう

パワートランスはISO製です チョークコイルは表記がないようですがISO製でない理由はありません

その他抵抗類はリケンとDALE、コンデンサーはEROとニチコンかニッケミです 

オイルコンがあるようですが用途が理解できないのでわかる方にご教示いただければと思います 内部画像を参照ください

知人の製作アンプですが詳細を教えていただけることはありません 使用せずに3台共に5年以上は経過しているようです 

どんな電気製品でも放置期間が長いと様々な問題点が発生します 本アンプも3日間ほど電源を入れ音出しを2日間行っても安定してい

ますが今後どのようなことが起きるかはわかりません メーカー製のメンテナンスシステムが整備されているわけではなくご自分で方策を講じなければならないのが自作アンプです ご自分で対処できる方の落札を望みます 


画像でご理解いただける方にお使いいただければと思います

ヒーターは全て直流点火です 動作と音質は安定していてノイズは聴こえませんでした ご本人の使用していた三菱2S-305改にて試聴しました 従って出力インピーダンスは16Ωと思います

知人製作アンプは3台あり、その中で最も音の良いアンプでした 当然のことですが、試聴スピーカー2S-305での比較であります


ご注意;発送は3月2日月曜日または3月7日土曜日・8日日曜日のいずれかになります 合わせてお支払いいただけると幸いです 引取りも同様です




ヴィンテージですが自作真空管アンプの扱いをご存知でないと扱うべきではありません。最低の知識は必要です。






お取引は、社会常識に範囲内で行いたいと思います。私にとって常識とは、出品者の設定した条件が、不当でなければ、入札・落札は了解して行うということです。中古の売買とは結婚みたいなものです。説明文を読まずに入札をするようなことがないように願います。


注意事項
届いて1週間以内に初期不良があれば、返品をお受けします。これも当然のことですが、真空管の再セッティングをしないで使用するなどの電気機器使用常識をお持ちでない方は電気機器に触れてはいけません 

返品をお受けする条件は返送料・送金手数料は落札者ご負担です。

受取連絡は受け取り後速やかに行ってください。ヤフオクのシステムを見る限り、返品・返金はヤフオクシステム外で行われるようです。受取連絡が無い限りクレームをかけてもヤフオクも出品者も対応しないようですし、受取連絡が遅れる分、対応も遅れるようです。

>代理入札落札される方へ:出品者の立場から申し上げます。ご商売でしょうから拒絶することはありません。しかし商売であれば、リスクを取らない方とはお取引をしたいと思いません。支払を速やかに行う、受け取り連絡も即行う等は、商行為として厳重に実行する最低の仕事です。多くの方々は理解されていらっしゃいますが、残念なことに本当に少数の方ですが、理解することできない方がおられます。二度は無いこともあると思ってください。



重要ですので、必ずご理解下さい。

ちょい読みで入札せずよくご検討の上落札してください。


発送詳細
在庫地は東京です。発送は土日曜日が基本です。

サイズは120で入ると思います 重量は20Kg程度でしょう 出来れば引取りを考えていただきたく思います

詰め込みすぎによる破損を考慮してサイズは大きめの方が良いとお考え下さい。

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.
