Thermionic Culture : 7 results priced between $1,500.00 and $10,000.00

The 3u 19" Thermionic Culture Earlybird 4 has a unique valve design, in that it uses Class A bias valves in a push-pull circuit, company founder and chief designer Vic Keary believes that this is one of the finest pre-amplifiers available today, and despite they're use for distortion in power amps, valves have better distortion and lower noise than solid state amps. Due to specially designed Sowter transformers the Earlybird 4 boasts well under .01% distortion, a Vic explains that "it's like connecting...

Following on from the success of the previous models including the red face anniversary limited edition the new model features new switched and stepped rotary controls for quick and easy recall. The input gain features a 24 position ELMA, a 11 position ELMA for the Threshold, 6 position ALPHA attack and release and a 31 position OMEG stepped output pot. The same side chain filter section as previous versions has been retained.

At the heart of the EQ is a baxandall type circuit, effectively giving 2 shelving equalizers, one for low frequencies and one for high frequencies. The EQ point of these shelves can be switched between 2 positions for each shelf. There is also a unique circuit, originally designed by Vic in 1960, which controls the amount of presence in the signal. This is a uniquely shaped, active mid lift type EQ. We've included a fixed frequency mid cut similar to that found in the Rooster. We've also included...

Input select (Mic Lo, Mic Hi, Line), Bass lift, Bass cut will give 2 positions of increasing bass shelving cut which interact with the bass lift to also give a variable mid cut overall. The Hi pass filter is purely for cutting very low problem frequencies. Top lift & cut, Presence, Gain, Hi pass filter, Phantom power (+48v). Note: Bass & Top lift controls use our Varislope curves which favour the extremes (40Hz & 10 kHz) when set high, which give heavy bass & glistening tops - unobtainable without...

Warm sounds gently or create a noise like a 200-watt guitar stack with all the drivers slashed. Independent channel operation. Odd or even harmonic distortion, or combination of both. All valve design free from solid state additives. High impedance line input or instrument inputs. 4kHz and 7kHz filters. Overdrive and bypass switches. Maximum output level: +17dBV. Distortion: 0.2% to 99.5%. Noise: Better than 75dB below M. O. L at typical settings. Input impedance: 30 kohms. Output impedance...

This Special Limited Edition Fat Bustard II is introduced for those purists who want the facilities of the Fat Bustard summing mixer (special equalisation for the mix, stereo width, bass to centre) but a little less colourisation and even lower distortion and noise, though not as much max "Attitude". The top response now extends to 50+ kHz with consequently less phase shift. It uses 12AY7 double triode input valves in place of 5965s. Both Fat Bustards have exactly the same 14 inputs, and same controls...

Thermionic Culture have released the Little Bustard, their second valve summing mixer which has been designed to complement the Fat Bustard valve summing mixer by increasing the number of inputs channels. Or the new 19" 2u Little Bustard can be used independently by itself as a stand alone mixer. Features include 16 input channels arranged as 6x stereo pairs with fixed gain at unity level with on/off switches, 4x mono inputs with mute switches and pan pots which can be defeated by another switch...
