 7段平滑回路基板 。全波整流 RK-199type4

商品説明

・およそ125台5球ラジオを造った経験を入れて、7段平滑回路を基板にしました。
・実装部品はご用意願います。
・RK-222・RK-227等 dc12.6のヘッドホンアンプ用電源基板です。
・トヨズミ HT-1605(16V 0.5A)を タカチMB-3に収納できる基板サイズです。
・KENWOOD PA36-1.2A(能動制御品)でRK-227を鳴らすとハム音がするので、基板化しました。結果、ハム音レスです。
・トランジスタ等の能動制御ですとラジオノイズが生じます。ラジオ工作派ですので、ノイズ源になる電源は使いません。
・シリコンブリッジはラジオノイズを確認できないメーカー型番を推奨しています。
・平滑回路はC総容量より段数が支配的です。
・抵抗は3Wサイズ。 Cは径18mm と13mm .  35v 10000uFは径18mmですね。
・35v 10000uFを7つ搭載する(計70000uF)とコンデンサー漏れ電流でトランスが熱くなったので、減らして3つに落ち着きました。
・R値は電源容量、電圧、消費する側の容量にて変えてください。

注意事項
定形外にて発送

その他
・回路図と部品配置図は付属します。
・平滑回路ケミコンのコールド側は一直線上に配置したほうが低ノイズになります。実態配線図で見掛ける渡配線式ですとノイズ高の傾向がありますね。
・この平滑回路を実装したラジオです。AC350V⇒DC200V化しています。

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.

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

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.
