Brand New LINLAI WE2A3 Vacuum Tube Audio Valve Replace 2A3 2A3C 2A3B Electronic Tube Amplifier HIFI Audio Amplifier Kit Diy Genuine Factory Precision Match Quad
Product features:
WE2A3 directly replaces any type of 2A3 pipe. It is a combination of WE300B and RCA single screen 2A3 audio quality. The WE2A3, developed on the basis of the replica WE300B with the same materials and processes, is strongly recommended for 2A3 players to try this WE2A3. It is more amazing to listen to the fine products, and the performance of high frequency is fascinating. Both have their own characteristics, both of which are the sound effects of the 2A3. You can listen to the comparison independently.
:
Soft and delicate, with high sound density, richer details, stronger analytical power, mature, stable and charming
Taste is irresistible.
WE2A3 directly heated cathode medium power triode is used for A1 Ab1 amplification.
