Psvane WR2A3:  a whole new substitute for 2A3, the world's first hybrid of WE300B and RCA single plate 2A3:
 
The WR2A3 tube is a whole new creation - it is not a replica of any tubes existed in the history before. WR2A3 was created to combine the bottle shape, structure and materials of Western Electric 300B with the electrical specification of RCA single plate 2A3 to get the best of both worlds. The end result is - a silky, open and extended top frequency that has never be available with any 2A3 tubes before.
