Premium NOS and modern production rectifier tubes 5U4, GZ32, GZ34/5AR4, 5Y3, 6X4 and other rectifier tubes
We test our rectifier tubes on a tube tester that tests each half individually to insure that both sides are equally strong.
This insures that our tube rectifiers will not cause any additional hum in your audio equipment.
