Both 5U4G and  U52 are the best selling valve here at Audio Magical.

We had many requests about this valve and its variation.

We thought it is our commitment to show all that is available for this directly heated full wave rectifier that saw the light in the 1940s.

With a rating of 500 Volts on the anode, the 5U4G U52 remains the best option for any vintage and modern set.
