The Groove Tubes Gold Series GT-5Y3|GZ30 is a rectifier tube common to lower-powered Fender amplifiers such as the Champ, Princeton and Deluxe amps. This Gold Series vacuum tube can be used in many 5AR4 and 5U4 amps for lower levels. This Groove Tubes rectifier may be used in amps such as the Matchless DC-30 series and similar amps when you want more compression, less attack, and to lower the voltages in these amps. The GT-5Y3 rectifier gives a nice feel to these amps with a much slower rise time than the 5AR4 or the 5U4, with a great feel. The Groove Tubes GT-5Y3 rectifier will also let amps such as the Matchless distort at a lower volume to make them suitable for smaller venues and to record sweetly at lower settings.
