octal based heated based biphasic HT rectifier valve
Manufacturers: Brimar , Cossor , GEC Valves , Osram
The 5Y3GT is a directly heated full wave rectifier, with suspended inverted V form coated tape as filaments. Recommendations on maximum reservoir capacitance are 32 µF and minimum series resistance re 100 Ohms respectively. The envelope has an approximate diameter of 28 mm and excluding the IO base pins the length is approximately is 68 mm. The type 5Y3G was first introduced in 1937.

The 5Y3G has exactly the same construction, however, The envelope has an approximate diameter of 32 mm and excluding the IO base pins the length is approximately is 100 mm The type 5Y3G was first introduced in 1937.

The U50 is GEC parlance for a 5Y3 – it is the U52 famous little brother again it is a directly heated full wave rectifier, again with suspended inverted V form coated tape as filaments. Recommendations on maximum reservoir capacitance are 32 µF and minimum series resistance are 100 Ohms respectively. The classic envelope has an approximate diameter of 45 mm and excluding the IO base pins the overall length is 100 mm. Type U50 was also first seen in 1937.
