The JJ 5Y3S Full Wave Rectifier Valve replaces all 5Y3GT types. “GT” means glass tubular and does not refer to the specification.”
Amps such as the Fender Champ and most of the early Fender Tweeds use this valve. In these amps, it’s better to avoid NOS (New Old Stock) 5Y3s which were not made to as high a specification as the modern JJs. Our JJ 5Y3S Full Wave Rectifier will perform well in all 5Y3 rectified amplifiers.
It is worth replacing the rectifier whenever you replace the output valves, as they lose emission and voltage with use. This leads to lower volume and bad sounding distortion.
We test each JJ 5Y3S on our suite of vintage, modern, and custom-built valve testers to assure maximum quality.
