GX-500HD(B) パワードスピーカーシステム
ブランド:ONKYO
発売日:2009/04/10

中古GX-500HDの整備・リフレッシュ品第三段、ラストです。
今回放出するGX-500HDの中でも目玉品になります。

この個体は、通電時間がごく短時間だったと思われます。(おそらく500時間以下)
使用に伴う爆熱トランジスタによる基板の焼けがほとんどなく、内部の電解コンデンサも爆熱部分以外は容量抜けがほとんど見られなかった良品となります。
修理にあたり、手を入れた部分も明らかに容量抜けが発生していた高温部の部品交換にとどめ、交換した電解コンデンサもオーディオグレードの部分にはオーディオグレード(85℃品ニチコンFG,FWシリーズ)のものを使用し、放熱対策の部品移設のみを施したほぼオリジナルのままの逸品です。
入手当初、スピーカーリレーの接点不良による不具合が出ていたので、前の持ち主は店舗で長期保管されていたものを購入したところ、リレー接点が劣化していたため最初から音が出たり出なかったりといった不具合が発生してすぐ使わなくなりお蔵入りしていたものと思われます。
左スピーカー天井後部に擦り傷、またシリアルシールに破れがあります。

ほとんどがオリジナルのまま、ということは、通電時間が短いとはいえ、内部に搭載されているオリジナルの電解コンデンサは製造からそれなりに年数が経っており、また85℃品のままとなりますので完全にリフレッシュ交換を施したものよりは耐用年数は落ちると思いますので、できる限りオリジナルの音質が欲しい方向け、と言ったところでしょうか。

左右スピーカーユニットを繋ぐケーブルは付属しませんので落札者様側でご用意ください。

整備点としまして下記があります。
・右スピーカー内吸音材交換
・リレー接点研磨修正
・7815、7915熱伝導グリス塗布
・9.1V、22Vツェナダイオード交換
・発熱の激しいトランジスタへのヒートシンク取り付け、足延長による移設
・発熱部品近接の電解コンデンサを基板裏面に移設

交換した電解コンは7815入出力部x2、爆熱トランジスタ周辺x4、7812周辺x1の7つのみです。
左右のDCオフセットはアンプ通電後温度が安定してから調整してあります。

上記修理後、他の大幅な変更を加えたGX-500HDとの比較基準機として多少運用したため、100時間程度の通電があります。

箱詰めする前に、デジタル光、RCA-A/RCA-Bでの入力でのスピーカー音出し、ヘッドフォン出力での音出し、ボリュームの実用上問題になるガリの有無、リモコンでのスタンバイON/OFF及びボリューム動作を確認してあります。

今回はちょっと値段が高め設定なので、新品の風量調節可能なUSB電源冷却ファンと、取付用の脚(磁石付き)をおまけにつけます。

中古のリフレッシュ品となりますので、傷やオリジナルとの相違に関して気になる方は入札をお控えいただきますようお願いいたします。
また、年末年始は落札されても発送まで多少お時間をいただくことがございますのでご了承ください。

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).

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.
