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.
Please browse through all we have including precious Mullard long cone long glass U52 (5U4G) and other variations.
We have two pairs of Marconi red logo, this is the large logo with tall glass type U52 5U4G.
The early plate tells these valves were made late 1940s early 1950s. Lovely design with black plate and cup getter, not to be missed!
Tested with AVO VCM 163 with A1=A2 100% emission
