Description
The U52 aka 5U4G is one of 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 U52 remains the best option for any vintage and modern set.
