KT88 Integrated 35W

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. The KT88 outclasses many much more expensive rivals. This amplifier is powered by KT88 Kinkless Tetrodes in 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.
