Marshall Amplification was founded in 1962 by Jim Marshall, who was a drummer and drum shop owner in London. The company’s first product was the Marshall JTM45 amplifier, which was powered by four KT66 power tubes. These tubes were manufactured by GEC/M-OV and were known for their reliability and long life. Since then, Marshall has been using various power tube types in its amplifiers, including EL34, 6L6, KT88, and others.
What are Power Tubes?
Power tubes, also known as output tubes, are responsible for amplifying the electrical signals generated by the preamp tubes and sending them to the speaker. They are the most important component of an amplifier, as they determine the tone, volume, and overall sound quality of the amp. Power tubes come in different types and sizes, and each type has its own unique characteristics and sound.

EL34 power tubes are known for their warm and rich sound, and they are used in classic Marshall amps like the JTM45, Plexi, and JCM800. 6L6 power tubes, on the other hand, are known for their clean and crisp sound, and they are used in amps like the JCM900 and DSL. KT88 power tubes are the largest of the three, and they are known for their high output and tight bass response. They are used in amps like the JVM410H and the vintage 2203.
How Power Tubes Affect the Sound
As mentioned earlier, power tubes play a critical role in shaping the sound of an amplifier. Each type of power tube has its own unique sonic signature, and choosing the right one can make a huge difference in the overall tone and character of the amp. EL34 tubes, for example, are known for their warm midrange and creamy distortion, while 6L6 tubes are known for their tight low end and sparkling highs.
