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 death. If you haven’t owned any tube before, we recommend you not to start with a...

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 KT88-TII HIFI Audio amplifier Vacuum tube a pair 100% Brand New 1, PSVANE T-Collection series MK II use the Carbon Microcrystalline technology. Carbon Microcrystalline is a kind of very stable absorbent (material), and it has excellent heat transfer performance. Carbon Microcrystalline make up stabilization of the electrical performance inside of the Vacuum tube.  2, The PSVANE T-Collection series MK II tube socket is made with Teflon. It is very low electric inductivity, very low...
