IWISTAO KT88 Single-end HIFI Vacuum Tube Amplifier 2x13W West Electric Master Manual Scaffolding Soldering
Model No: WVT-WEMAKT88
It is said that this famous European tube KT88 and its big brothers KT100, KT120, KT150 are all world-renowned tubes, these famous tubes are used by the world's top manufacturers, such as the United States mcintosh.
But for cheap manufacturers, it will feel pressure and fear to use this tube , because some sounds are too rough, in fact, for many reasons, they are not designed well. What's more fatal is that the circuit design is unreasonable. GE company stipulates that the input impedance of kt88 is not greater than 270K. If it is driven by a high-level U tube, it is a serious impedance mismatch. If it is 6SN7 (6N8P), the two-stage common negative design output impedance is also fast to the peak, the distortion of KT88 is fed back to the first stage, and the distortion becomes larger after being offset with a 6N8P low U tube feedback.
So if you want to get better sound from tube KT88, it software and hardware must do well. Our circuit design use the tube 6J8P (6SJ7) + 6N8 cathode output to drive tube KT88. No matter its gain distortion or impedance is matched, it is seamless! The well-designed KT88 tube amplifier gives the impression that the music is delicious! Delicate sound and strong penetrating power! High school, low frequency and so on all have very good performance.
