Ignite your sound with the Tube Amp Doctor's 5U4GB Premium - Rectifier Tube, a venerable powerhouse from the rich history of American guitar amplification.

Encased in a straight glass envelope, this rectifier tube pays homage to the vintage USA-made guitar amps that dominated from the golden era of the 1950s to the 1970s.

  • Plate Current and Amplification
  • Low Noise
