Psvane WR2A3 Valve, matched pair

The Psvane WR 2A3 is based upon the original Western Electric valve though with a slight twist. It combines 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.
