Aries Cerat Incito tube preamplifier

The heart of the Incito preamplifier is a zero feedback power gain stage, which is consisted of a transformer-coupled super-triode, using the ultra high trans-conductance E280F which was only made by Siemens. This superb tube is loaded with a highest quality step down transformer. Measuring data speak for themselves for this highest quality combination.

Voltage swings of over 320V are easy task for the power stage, and is stepped down to 80Vpp, while keeping transistor-like noise figures. Our step-down transformer provides very low output resistance and more than adequate current to drive any load down to 250 ohms!

The power supply is built around the 5AR4 rectifier, with separate double pi filtering for each channel,using oversized chokes ,and high speed capacitors, along with an ultra low noise adjustable bias supply.

A high quality discrete ralay-latched-resistor attenuator is used ,accompanied with supreme quality signal relays. True balanced outputs are standard , and all inputs are custom configurable.
