UK-EL34 is a high-performance audio output pentode, its anode limited dissipation power is 25W. The output power is more than 10W when it is for Class A1 amplification as a single tube in audio amplifier.The output power more than 35W when it is for Class AB1 amplification.  

Classification-Dome-type or Aubergine-type bulb of glass, a white ceramic base with four-prong bayonet gold pins , oxide coated filamentary, solid plate, mesh plate, cabon plate triode.  Application-Audio frequency amplifier where power outputs of approximately 8.5watts or less is required at relatively low plate voltages.  Dimensions-Dimensions, outline diagrams of the tube and bases, and the arrangement of electrode connections to the base terminals are shown in Figures 1, 2 and...

These are the latest release from Psvane Audio as their affordable series for everyone.  It inherits the warm sound of Chinese KT88 tubes compared to the dry sounding Russian tubes, but also offer you incredible details at a small price tag.  Features:  Clear glass enclosure  Gold coated pins  Can replace all standard Shuguang KT88 tubes  Factory matched quad or pair – each tube packed in its own box  Some precautions about using high voltage power...

PSVANE (Noble sound) launched in 2011 the history of complete engraved the Western Electric WE300B vacuum tube. The PSVANE for Original work. Then laid its global audio vacuum tube position in the area. Since, Launched a series of beautiful sound of vacuum tube PSVANE classical sections, Becoming the world's top vacuum tube brands .  According to third-party statistics in the field of high-end and top vacuum tube , PSVANE is always the first of the world 's sales .In addition, as a Chinese...

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...

The major difference seems to be that the Psvane is far more extended at the frequency extremes,but at the same time has a far more richer harmonic presentation. Much like the qualities of NOS 845′s  In comparison to the others, the 845T, right out of the box, seems brighter. After about 10 hours I began to notice a difference. Compared to the 845B, they seem far more transparent but at the same time much cleaner. Bass tones and pitch definition are improved. String tone seems to be...

PSVANE 805A hifi Audio Vacuum Tube a pair amplifier tube 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.
