EVALUATION & DEVELOPMENT PROGRAM
for
CLASS-D TUBE AUDIO POWER AMPLIFIERS

An electronic audio power amplifier
can be built using
solid state semiconductors or vacuum tubes active devices.

These can be connected in
linear or switching circuits.

That means we are able to design:
- linear amps made by tubes
- linear amps made by silicon
- switching amps made by silicon

The fourth arrangement seems to be missing:
- switching amps made by tubes !

The SWITCHINGLOW PROJECT shows how the AmpDiVa Technology
allows this fourth arrangement can be done.

AmpDiVa Technology

**Be ready to discover a new land !**
The SWITCHINGLOW Project allows professional researchers, designers and developer to approach the AmpDiVa Technology. This completely new technology, that allows the use of vacuum tubes as power switching devices in the bridge circuits of a Class-D amplifiers, has been disclosed in public for the first time at the European Maker Faire 2015 in Rome. It depicts an unexplored land full of promising new achievements. It is the missing junction between the world of vacuum tubes, apparently bounded only to the analog domain, and the digital one. It is the missing fourth cornerstone in the design of audio amp after the well know vacuum linear, semiconductors linear and semiconductors switching circuits. A new land to discover in all its emotional perceptive involvements between Arts and Science. The Project allows the Technician to join the discovery of this new world starting from a working affordable evaluation platform offered at a reasonable cost.
