Replacement Tubes (Valves)
There are three main categories of tubes. These being driver (preamp) tubes, power tubes and rectifier tubes.
Driver Tubes (Triode): A driver (preamp) tube will amplify the signal and prepare it for further amplification by the power tubes. There are several models that we offer. These include the 12AX7, 12AT7, 12AY7 and 12AU7. Besides tonal variations, one of the primary differences is the gain factor. This is as follows: 12AX7 = 100, 12AT7 = 60, 12AY7 = 45 and 12AU7 = 20.
Power Tubes (Tetrode or Pentode): Power tubes further amplify and drive your signal to power larger speakers. Some common models include the EL34, KT88, KT120 and KT150. Different tubes will provide varying tonal qualities and output power.
Rectifier Tubes (Diode): Rectifier tubes convert AC into DC, which the amplifier requires as a power source. Please note that not all tube amplifiers require a rectifier tube. Some amplifiers will use a solid state rectifier or perform rectification within the transformer.
