Epicycloid Engineering Turbo Entubulator

The Turbo Entubulator is Epicycloid Engineering's flagship module: a tube breakout module that can produce effects ranging from simple VCA-like behavior all the way to gnarly tube distortion, wavefolding, and more. By providing direct, patchable access to the tube's pins, one can create a number of novel behaviors that all exploit the brilliant and peculiar nonlinearities of the included 6AR8 tube.

The Turbo Entubulator provides static and CV control of Deflector Bias and Offset as well as Grid Control and Screen voltages, allowing a number of patchable tube effects. Built-in cathode bias controls and automatic gain control help to reign in particular behaviors from tube distortion to nonlinear waveshaping.

The Turbo Entubulator requires connection to the Epicycloid Engineering Illumonix Prime power supply.

Epicycloid Turbo Entubulator & Voluptron Vacuum Tube Eurorack Modules
Epicycloid Engineering has two vacuum tube based modules and a dedicated power supply module for them. The Turbo Entubulator is a module that breaks out all of the functions of a 6AR8 tube to be voltage controlled and used with your other eurorack modules. This module can be used as a VCA, ring modulator, distortion/saturation effect, waveshaper and probably many other uses when patched in different ways.

The Voluptron is a four pole lowpass ladder filter, but with tubes instead of transistors.

Both of these modules receive 200V power from the Illuminox Prime module to make sure the tubes are running at full power.
