The 13V10 is a type of pentode tube. It is a compact, high-performance amplifier tube with a maximum power rating of 10 watts. It is a preferred choice for guitar amplifiers, PA systems and other audio applications. It is a very reliable tube that produces a rich, full sound. The 13V10 has three grids (control grids, screen grid and suppressor grid), and two plates (control plate and screen grid). All of these grids and plates are responsible for the sound you get out of the tube. Its construction makes it highly reliable and capable of taking the heat and distortion of most musical styles.
