PSVANE hifi Audio vacuum tube 805 HIFI amplifier tube a pair 100% Brand NEW
The price is for 1 pair (2 pcs), if you buy 2 pair(4 pcs), we will send the Factory full matched tubes to you.

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 resistivity, high arc resistance. It has a lot of excellent features, it is waterproof and dampproof, withstand high temperature, low temperature resistance and Anti-corrosion. So, It enhances the stabilization and service durability of the vacuum tube.

3, The gray color of the PSVANE T-Collection series MK II tube is made with Aluminum oxidation, never discolor never color deterioration.

4, The feet of the PSVANE T-Collection series MK II tube are made with New formula Real gold plating. It Enhance the performance of the connection part of the contact. It makes the weak signal loss is reduced to a minimum.

805 direct thermal thorium tungsten cathode transistor, can be used for Class B, A-F, R-F power amplifier , Class C R-F power amplifier and high frequency oscillations.
