Vacuum Tube VCO
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 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 sound 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.
The tubes protrude 42mm.
