Newly I have plan to build up one of single ended amplifier monoral single ended amplifier EL11/EL12 EL11 is 4.5W EL12 is 8W rms
deliver out out power .small room so I do not have any much power.
小さい部屋限られた予算ですよってモノラルアンプの製作にする計画です。部品は全て持っています。ソケットは最近他の事に使った為に 部品販売業者の球露屋さんから入手しました。
回路図は追って紹介しましょう。低バイアスのヨーロッパのペントードですので難しい回路は必要がありません。生活保護でもアンプは作ります。貧困でまして一人で生きるのは難しい
EL34は とても EL12 や EL11の真空管に似ているのです。EL34でも低グリッド バイアスで中高圧で使うことにより似た特性が出ます。皆さん知らないだけです。
EL34 はこれらのヨーロッパのペントードを頭に入れて開発された純正のオーディオ用の真空管なのですと私は思っています。
このEL11は何か直熱管の音が出るのです。基本的にはEL3N に似ている特性ですが、点火してから音が出るまでかなり早く音が出るのです。つまり熱効率が良いか若しくは直熱管です。
このことは何回も言っています。EL11に限って特別なペントードです。素晴らしい直線性のある真空管です。残念なのは１本しか持っていません。不思議なペントードです。
I'm planning to build a mono single-ended amplifier using EL11/EL12. The EL11 delivers 4.5W rms, while the EL12 delivers 8W rms.
I don't have much power. I
have a small room and a limited budget, so I don't have much power. I already have all the parts. I recently used the socket for something else, so I got it from a parts retailer called "Tamaro-ya."
I'll show you the circuit diagram later. It's a low-bias European pentode, so no complicated circuit is necessary. I'll build an amplifier even on welfare. Living alone in poverty is difficult.
The EL34 is very similar to the EL12 and EL11 vacuum tubes. The EL34 also exhibits similar characteristics when used with a low grid bias and medium to high voltages. It's just that people don't know about it.
I believe the EL34 is a genuine audio vacuum tube, developed with these European pentodes in mind.
This EL11 produces the sound of a directly heated tube. Its characteristics are basically similar to the EL3N, but the sound comes out much faster after ignition. In other words,
it either has good thermal efficiency or is a directly heated tube.
I've said this many times. The EL11 is a special pentode in itself.
It is a vacuum tube with wonderful linearity. The only unfortunate thing is that I only have one. It's a strange pentode.
EL12 pentodo 8 W valve just like EL156 small size tubes
