Abstract

PROBLEM TO BE SOLVED: To increase the gain of a preamplifier circuit in a vacuum tube amplifier for musical instruments such as a guitar amplifier by increasing the number of signal amplification stages in series in the preamplifier circuit included in the amplifier itself without any of the increase in vacuum tubes or change of vacuum tubes and modification involving soldering.SOLUTION: The invention uses a channel in one side of a vacuum tube amplifier for musical instruments having multiple independent channels, changes the order in which a signal flows in a circuit by connecting a vacuum tube socket 11 for a composite tube and a preamplifier vacuum tube 12 to a device of the invention, uses an amplifier circuit part in the other unused channel side for signal amplification of the channel in the used side, and thereby increases the number of amplifier circuit stages in series.

Description

本発明は主にエレクトリック・ギターなどの楽器用アンプに見られるプリアンプ回路の改造に関する。   The present invention mainly relates to a modification of a preamplifier circuit found in an amplifier for an instrument such as an electric guitar.

ギター・アンプなどの楽器用アンプは、オーディオ用のＨＩ−ＦＩアンプとは違い、音の信号を歪ませる事で楽器としての音色を作る特徴がある。   Unlike an HI-FI amplifier for audio, an amplifier for a musical instrument such as a guitar amplifier is characterized by creating a tone as a musical instrument by distorting the sound signal.

ギター・アンプなどの楽器用アンプは、特に真空管回路で歪ませた音色がより音楽的であるとして、上位機種を中心に現在でも真空管アンプが主流である。   As for the amplifiers for musical instruments such as guitar amplifiers, vacuum tube amplifiers are still mainstream, especially high-end models, because the tone distorted by the vacuum tube circuit is more musical.

真空管の種類の中には、真空管１本で２本分等の複数本分の働きを持たせた複合管があり、特にギターアンプ等の楽器用アンプのプリアンプ部の回路で使う真空管としては、最も一般的である。具体例として真空管名をあげるとＥＣＣ８３などがある。   Among the types of vacuum tubes, there is a composite tube that has the function of multiple tubes, such as one tube, especially as a tube used in the preamplifier circuit of a musical instrument amplifier such as a guitar amplifier. The most common. As a specific example, there are ECC83 and the like when a vacuum tube name is given.

ギター・アンプなどの楽器用アンプの中には、より多くの歪が得られるよう、回路内で音の信号の電圧を増幅する増幅回路の段数を直列により多く配列させた物があり、それらは一般的にハイゲイン・アンプと呼ばれている。   Some amplifiers for musical instruments such as guitar amplifiers have a series of amplifier circuits that amplify the voltage of the sound signal in the circuit so that more distortion can be obtained. It is generally called a high gain amplifier.

ハイゲインにする改造等での回路の変更で電圧増幅段数をより多くする為に回路の真空管の増幅段の絶対数を増やす方法があるが、その場合は既存の真空管だけでは数が足りなくなるので、真空管を追加するか又は既存の真空管より多くの増幅段数を持てる別の複合管と交換する必要が出てくる。
There is a method to increase the absolute number of amplification stages of the vacuum tube of the circuit in order to increase the number of voltage amplification stages by changing the circuit by remodeling to high gain, etc., but in that case, the number is insufficient with only the existing vacuum tube, It may be necessary to add a vacuum tube or replace it with another composite tube that can have a higher number of amplification stages than an existing vacuum tube.

ハイゲイン・アンプが出てくる前の時代のビンテージ・アンプや、ビンテージ・アンプの復刻版を含めハイゲインではないタイプの楽器用真空管アンプの中には、例えば高音が強調されたチャンネルとノーマルの２つのチャンネル等、複数のチャンネルが用意された物が多く生産されていて、これらのアンプで回路内の信号の電圧増幅回路の増幅段の初段が独立してそれぞれのチャンネル用に並列に配置された設計の物が多く普及してある。本発明装置の対象のアンプでもあるそれらのアンプの例として次の非特許文献１を挙げることができる。   There are two types of tube amps, such as a channel with emphasized high frequencies, and a normal one, among vintage amps of the era before high gain amps appeared, and non-high gain type tube amps including reprints of vintage amps. Many products with multiple channels such as channels are produced, and these amplifiers are designed so that the first stage of the amplification stage of the signal voltage amplification circuit in the circuit is independently arranged in parallel for each channel There are many popular products. The following non-patent document 1 can be given as an example of those amplifiers that are also the target amplifiers of the device of the present invention.

Ｍｉｃｈａｅｌ Ｄｏｙｌｅ著 「Ｔｈｅ Ｈｉｓｔｏｒｙ Ｏｆ Ｍａｒｓｈａｌｌ」、第１９７頁〜第２０６頁、第２０８頁〜第２０９頁“The History of Marshall” by Michael Doyle, 197-206, 208-209

上記で述べたアンプで、高音が強調されたチャンネルとノーマルの２つのチャンネル等の複数のチャンネルがあっても実際にはどちらか一方の好みのチャンネルのみを使うユーザーも多い。その場合もう一方のチャンネルは使わない事になる。   In the amplifier described above, there are many users who actually use only one of their favorite channels even if there are a plurality of channels such as a channel with high-pitched sound and two normal channels. In that case, the other channel is not used.

本発明の目的は、真空管の追加又は真空管の種類の変更やアンプ自体に半田付けを伴う改造の何れもする事無く、アンプのプリアンプ回路部分の増幅回路の段数を直列に増やす事にある。   An object of the present invention is to increase the number of stages of amplifier circuits in a preamplifier circuit portion of an amplifier in series without adding a vacuum tube, changing the type of vacuum tube, or modifying the amplifier itself with soldering.

独立した複数のチャンネルを持つ楽器用真空管アンプの片側のチャンネルのみを使用し、複合管の真空管ソケット１１とプリアンプ用真空管１２を本発明装置に接続して回路内での信号が流れる序列を変更させ、他方の使用しないチャンネル側の増幅回路部分を使用する側のチャンネルの信号増幅の為に使わせて増幅回路の段数を直列に増加させる。 Using only one channel of the vacuum tube amplifier for musical instruments having a plurality of independent channels, the vacuum tube socket 11 of the composite tube and the vacuum tube 12 for the preamplifier are connected to the device of the present invention to change the order in which signals flow in the circuit Then, the other amplifying circuit portion of the unused channel side is used for signal amplification of the channel on the using side, and the number of stages of the amplifying circuit is increased in series.

本発明は真空管の追加又は真空管の種類の変更やアンプ自体に半田付けを伴う改造の何れもする事無く、アンプのプリアンプ回路部分の増幅回路の段数を直列に増やす事を可能にする。   The present invention makes it possible to increase the number of stages of amplifier circuits in the preamplifier circuit portion of the amplifier in series without adding a vacuum tube, changing the type of the vacuum tube, or modifying the amplifier itself with soldering.
