Freedom to experiment

The Turbo Entubulator takes a beam deflection tube — first used to make simple and reliable analog multipliers in the 1950s — and gives you access to all its terminals to explore its audio potential.

A classic sound reimagined

We all know the sound of Bob Moog's transistor ladder filter. The Voluptron is the first vacuum tube version of this filter, combining its depth of timbre with the soft clipping of tube circuits.

Clean, safe high voltage

Some tube hybrid gear uses low plate voltages that don't bring out the proper tube sound. The Illuminox Prime uses a unique architecture to provide 200 volts for proper excitation, without running high voltage cabling through your rack.
