Parameter：  The long waiting of the American WE300B re-issue from USA seems endless; but now Chinese tube manufacturer Psvane Audio has stepped up to make a 1:1 replica of the original WE300B.  According to Psvane Audio, the Psvane WE300B Replica is: “100% 1:1 replica of WE300B, including materials, structure, internal and external size – up to the detail of a tiny screw used”.  Sample production run in Dec 2011 with test launch in China and Japan on Jan 8th...

Psvane WE300A Vacuum Tube HiFi electronic Valve Factor Matched Pair(2pcs) 100% brand New Feature:  Directly heated cathode medium power triode, parameters and dimensions refer to 300B, for Class A1 amplification. It is suitable for 10W output power in audio amplifier. Similar to 300B, 300BN and WE300B, they can be used interchangeably.

Notice: the price is just for one tube,if you want to matched pair, please buy two tubes Some precautions about using high voltage power tubes:  Unlike other vacuum tubes such as KT88 or EL34, which typically run at 450V plate voltage, high voltage power tubes such as 845, 805 and 211 run at plate voltage 900V or even higher depending on your amp design. Due to the high voltage in the circuit, biasing an 845 / 805 or 211 amp improperly may expose you to lethal high voltage causing instant...
