Listen to Jimi Hendrix songs the way they were intended to be heard in the 60s with the RCA 5814A tube and tube socket in your amplifier. This model of glass tube is popular with musicians who enjoy the way it treats low bass notes and provides a warm timbre for the guitar. Some tubes use three black mica base plates, and others may have gray. Whether you prefer using vintage tubes in your amps or maintaining a vintage radio, the RCA 5814A is a great choice. This double-triode tube is capable of handling up to 12.6 Volts.
