KT88 Power 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. Based around the classic KT88 valve in Push Pull Ultralinear configuration, this astonishing amplifier develops over 35 Watts of clean power with a beguiling musical performance. The KT88 valve has been used in many a classic amplifier since GEC developed it in the 1950s, and our implementation is a fine way to get the very best from the valve. The XL upgrade option features boutique components such as Schottky diodes for both main rectifier and heater supplies, Pi filter DC heater supply, Soniqs ICT signal cables, Soniqs SAX signal path and Rifa Low ESR Power capacitors.
