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...

The difference between WE101D and WE101D-L is pin, WE101D needs to match original WE-style tube socket, while WE101D-L only need flat quadrangle tube socket.

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...

805A-T is direct-heated type thorium tungsten cathode triode, can be used as class B, A-F, and R-F power amplification, class C R-F power amplification and high frequency oscillation. Heater Uf: 10 V If: 3.25 A Direct Interelectrode Capacitances input: 8.5 PF output: 10.5 PF grid to plate: 6.5 PF Maximum Rating Ua: 1500 V Pa: 125 W Recommended Operating Conditions (reference value) class B(A-F) for two tubes typical working condition limited parameter Ua: 1250 1500 1250 V Ia (mAx.sig per tube):...

Description: This pair of power monoblocks are designed with 300B tube to drive a pair of 845 vacuum tubes to produce beautiful midrange but with loads of power. It is designed to address audiophile's complaint that '300B amps are not powerful enough to drive those non-high efficiency speakers, but I still want the 300B sound'. The double power single ended 845 power will overcome those limitations, so that even with a pair of 84-89dB regular efficiency speakers, you can still enjoy the silky...
