Thermionic Culture Vulture 20th Anniversary Limited Edition – Discontinued

SKU: TCV20Av Categories: ,


The Culture Vulture 20th Anniversary product has been replaced by the Thermionic Culture ULTRA Vulture.


The 20th Anniversary Limited Edition of the Thermionic Culture Vulture. This limited edition produces much lower background noise, using Sowter transformers to balance line inputs and outputs, also indented pots for easy recall and also features an extended top end making this Culture Vulture perfect for mastering. The Bias control varies the current through the “distortion” valve (6AS6 type) and this current is shown on the millametre. At low current the Vulture is “starved” and the sound is inclined to be thinner and “break up” easily.

High current and the Vulture is over-fed and becomes quite fat and bloated. At medium current (0.25-0.3 mA) it distorts least, and this is the best setting for just “warming up” a sound. When the Vulture is over-driven, the meter may “twitch” and this gives a good indication of how drastic the distortion is.

The Low-pass filter has a 12dB/octave slope and will remove unwanted frequencies above 6 or 9 kHz (selectable) so as to make the sound more “rounded”. The Drive control and Overdrive switch give the user ample control over the amount the input signal is boosted before it hits the 6AS6 valve.

The Output Level controls the amount of signal going to the output valve. This control should be set at 8 + for low distortion and turned back when Drive is increased for more distortion, except when P2 is selected. The Bypass switch completely bypasses the unit so that the Culture Vulture’s effect can be accurately compared to the original.
