Psvane WE275

Chinese Psvane WE275
Psvane WE275 and WR2A3 Replica both are substitute for 2A3 tubes on auto biased tube amps. It is worth to mention that WE275 replica has negative grid voltage -60V, not the standard 2A3’s -45V. In a manual bias 2A3 amp, the bias current has to be adjusted to avoid red plate happening on the WE275 replica.
