PSVANE UK KT88 Audio Valve Vacuum Tube /6550/KT120 Audio Valve Vacuum Tube Amplifier
The KT88 fits a standard eight-pin octal socket and has similar pinout and applications as the 6L6 and EL34. Specifically designed for audio amplification, the KT88 has similar ratings to the American 6550 which was designed for use as a servo amplifier. It is one of the largest tubes in its class and can handle significantly higher plate voltages than similar tubes, up to 800 volts. A KT88 push-pull pair in class AB1 fixed bias is capable of 100 watts of output with 2.5% total harmonic distortion or up to about 50W at low distortion in hi-fi applications. The transmitting tubes TT21 and TT22 have almost identical transfer characteristics to KT88 but a different pinout, and by virtue of their anode being connected to the top cap have a higher plate voltage rating (1.25 kilovolt) and a higher power output capability of 200 watts in class AB1 push–pull.
The screen grid is sometimes tied to the anode so that it becomes effectively a triode with a lower maximum power output.
Up till now, PSVANE has been the lead and noble in the field of
tube sales. Not only had it been well received by users, but also
even some amplifiers at home and abroad has had upgraded to add
PSVANE as a selling point.
PSVANE always front in R&D of tubes. Till 2013, PSVANE has
accumulated the power to launch nearly 10 types of new items
constantly, and all types are the tops in market, which gained
numerous praises.
As the most promising products, three new items naming UK are ready to have a grand listing.
UK-EL34, UK-KT88, UK-6SN7, which are PSVANE HI-FI series, have the greatest cost performance that have never seen in history.
