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...

The difference between PSNAVE WE205D or WE205D-L is pin.  WE205D needs to match original WE-style tube socket,  WE205D-L only need Normal tube socket.  Specification:  Electrical parameter rating value unit  Direct Interelectrode Capacitances  Input 4.8 uuF  Output 5.2 uuF  Grid to plate ≤ 3.3 uuF  Typical operating parameter  Heater voltage 4.5 V  Heater current 1.6 A  Ua 300 V  Ug -30 V  Ia 8 mA  Amplification...

Psvane HIFI Series UK-KT88 /UK-EL34/UK-6SN7 are new-creation, never have the better cost-effective in the history of Psvane. After almost one year time, these HIFI UK Series vacuum tubes were come out by development team of Psvane The three model tubes are adopt the most UK sound charms of” Mould screen” plate material, and join into the symbolic music and the extremely emotional appeal sound performance of Psvane.this will be most music you hear with the same price of vacuum tubes.

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 dielectric loss, and high breakdown voltage, high electric volume...

These are the latest release from Psvane Audio as their affordable series for everyone.  It has dual triode section as a direct heating tube. Compared to the dry sounding Russian tubes, these tubes offer you incredible details at a small price tag. It also provides better low frequency control than generic Chinese 2A3B tubes.  Note: Chinese 2A3C tubes are not exactly the same as 2A3 or 2A3B tubes in terms of structure or specification. This Psvane HiFi series 2A3 can directly replace...
