The beam power quadrupole KT88 has an anode ultimate power dissipation of 42W. In the audio amplifier, two tubes can achieve 100W power for the AB1 push-pull output, and KT88 can also be used in the electronic voltage regulator circuit. KT88 is similar to CV5220 and 6550 and can be used interchangeably.

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...

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...
