(15W) or the more powerful KT88 model (35W). They are based on the integrated amplifiers, without input switching. Both are available with our XL
upgrade option which adds audiophile components where they matter most. Our designs use auto bias for ease of set up and long valve life. For built

Power Amplifier Kits
KT88 Power 35W (Class A)
This is our flagship amplifier and is an asset in any music system. A perfect blend of power, control and subtlety makes
this an amplifier that you forget is there. Combining the inherent musicality of Class A operation with high quality components, the KT88 outclasses many much more expensive rivals. This amplifier is powered by KT88 Kinkless Tetrodes in a Class A Push Pull Ultralinear configuration. The KT88 valve was designed by GEC as a high quality audio power valve, and this is an excellent example of how to get the best from that valve.
