ONKYO T-427 同調点調整 帯域トラッキング メンテナンス動作品




商品詳細
■商品概要
ONKYO Integra T-427。新開発のFM帰還方式を採用したFM/AMチューナー。FM帰還方式は、検波器出力信号の一部を、FMサーボ回路を通して局発へフィードバック(帰還)し、局発に内蔵した低歪率回路で局発信号を変調。変調された局発信号はミキサーで入力信号とミックスされ、IF信号が取り出されます。FM帰還方式では、IF回路の帯域幅を2倍に拡げたのと同じ効果があり、IF回路の最も位相特性の良い部分だけを通る事ができます。これによりIF回路のダイナミックレンジが拡大し、オーバー変調時の大入力に伴う広いIF信号帯に対しても、低歪率を維持できます。

他にも、信号のクリア化によるMPXでのセパレーションの向上、IFの広帯域化によりサーボロック方式の効果が高まり、同調精度が上がるなどの特徴があります。

ロック機構にはサーボロック方式を採用しています。

L/Rのオーディオ信号へ分離するMPX部には、安定度の高いAFアンプ内蔵・PLL・ICを使用しています。また、ここでのわずかな歪の発生を抑えるため、PLL・ICに強化フィルタを追加し、MPX径全体としての低歪率化を徹底しています。

■商品状態
正常動作品をメンテナンス調整した動作品です。テスターと信号発信器、オシロスコープを使い調整をしています。高級なチューナーも発売から40年もメンテナンスしないと受信同調点やトラッキング、セパレーションがずれ、本来の性能を発揮できません。さすがに随所でかなりずれがありました。調整していくうちに受信性能や音が格段に良くなりました。

FM部調整部
中央点83MHz同調点調整
帯域両端 76MHz・90MHz トラッキング調整
高調波歪率補正
QR 検波調整
ステレオ分離セパレーション調整

AM部調整部
OSC トラッキング調整
RF トラッキング調整
IF 調整

外観、内部とも破損はなく、比較的状態は良いです。天板に細い傷があります。ボタン類はすべて反応します。調整後、SN比や歪感、音の広がりが改善されました。同程度のシンセサイザーチューナーよりバリコンアナログチューナーの方が深い音がするイメージです。部屋を薄暗くするとランプやインジケーター部が浮き上がり独特な雰囲気に引き込まれます。

チューナーの受信は電波状況に左右されます。本体のみで付属品はありません。写真ではわからない傷や汚れなど、使用感のある中古品であることを理解の上、入札願います。

International Shipping Methods
Singapore Package Import: Customs and Tax Policies
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-holdings.com 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.
