(音門ラボ)71Aドライブ VT62/801A 真空管アンプ  無帰還

(音門ラボ)71Aドライブ VT62/801A 真空管アンプ 交流ヒーター クラスA (O.U.D.D.C) 無帰還です。



音門ラボにて独自開発されたドライブ管が直熱管となるO.U.D.D.C方式を採用して、VT62アンプが出来上がりました。



初段に396A(5670)となります。



音楽性を重視したので、出力管のヒーターはAC(交流)ヒーターとしました。ノイズのレベルは僅か0.3mV以下なので、ハンム、ノイズを全く心配なく、感度の高いホーン・システムでも音楽がないときでもとても静かです。



出品する前にメーカー(音門ラボ)にて点検を行い、動作的に新品の状態に戻りました。中古品なので、トランスに傷、汚れがありますが、全体的にきれいな状態です。メーカーの保証は3か月となります。音門は日本のメーカーです。メーカのHPはhttps://otomon.netです。詳しくはホームページにアクセスして情報をご参照ください。





仕様:(メーカーにて測定)



対応周波数: 16Hz~ 45KHz @8W/8Ω

残留ノイズ : 0.3mV以下

サイズ:W450xD350xH230mm



出力管はACヒーターのものの、ハンム、ノイズがなく、情報量が豊の音が出ており、クラシックからジャーズまで、音の妥協がなく、ボーカルと楽器の音色が美しいです。ドライブ管は71Aの直熱管を採用することにより、音の厚みが素晴らしく、音楽性が優れるアンプとなります。



調整ボリュームがついていので、プリアンプは必要ないです。



電源ケーブルを付属しません。



真空管の構成



初段:396A(5670)

ドライブ段:71A

出力段:VT62/801A

整流管:5U4、5AR4、GZ34



真空管は付属しないので、落札者に用意していただきます。



測定の情報を説明します。



最大出力: これは音楽が鑑賞できることを前提して出力を図る。通常は歪率が5%を超えない時、これは物理的な最大の出力ではありません。



残留ノイズ:標準的に真空管アンプは残留ノイズが1mVの程度であれば支障がなく音楽が鑑賞できます。そのレベルより低いほど良いです。100db以上の感度の高いスピーカーならやはり残留ノイズが0.5mV以下出ないならハンム、ノイズが感じます。自分のスピーカーの情報を確認してアンプを選択してください。
