When is Ultimate Ever EZ?

  Now. Check this out: at the front we have the controls and the power supply. All the digital bits flow across those ribbons to selector (left), volume (right) and the audio signal board (chassis back). The audio signal board uses end-to-end analogue potentiometers to adjust volume and vacuum silver relays to select source. TheRead More

Chazz2 – Headphone Amplifier

Introduction You may remember the Chazz. It used EL34/KT88 and 6SN7 (earlier versions 6SL7) and output transformers. Eventually we sold out and it was right at the time when chassis and transformer parts costs were escalating; our attentions were diverted to reworking our whole lineup to work within the new economic realities. The Chazz2 makesRead More
