Orpho OUROBOROS | Vacuum Tube VCO Eurorack Module

Published on Feb 2, 2020 HOX808

"In the OUROBOROS, the ECF 80 triode pentode is used in duplicate. It was originally intended as a TV and radio tube, but was also used in power amplifiers. Now we have revived them for the Eurorack. Even if a tube oscillator consumes a lot of electricity and its habit is always somewhat extravagant, it is worth starting up. Unique sounds are available for noises research.

Due to the 'curved' characteristics of the tube oscillator, the module does not have an exactly defined control characteristic (e.g. V / octave). The inevitable tolerances of the tube oscillator will also cause each module to sound a little different.

Connections:
2 x CV input for frequency control with attenuator.
IN - signal input / sync with attenuator.
Out - signal output. Scope frequency range high / low
3U high, 12HP wide, 30mm deep. Caution! Outstanding module! 42mm from front panel.

Power consumption: 12V | 400mA! 800mA during the warm-up phase (approx. 30 seconds).
