Expander for "G-Force" Tube Bass Amp and EQ

1U - Expander for Tronix-Audio "G-Force", the fully analog discrete TUBE BASS AMP module for Eurorack, aiming to be one of the best sounding tube modules on the market.
G-Force works as 2 discrete VCA-channels, and also as a saturation module, a Bass-EQ, a tube compressor and, if necessary, as a distortion unit.
G-Force uses a dual triode vacuum tube and 2 discrete (transistor) VCA circuits as active elements.
Discrete transistor circuits are always temperature-sensitive, thereby constructing minimal variation in touch response. Vacuum tubes are somewhat sluggish and also very temperature dependent. Depending on all control parameters, G-Force can add more warmth and volume to the sound.
Conclusion: This amp LIVES and has its own groove and character!
Gforce always processes the full input material because the two transistor VCAs are only at the end of the signal chain. This exploits the full potential of the double triode tube. The feedback path can increase the gain many times over. Depending on the EQ setting, the feedback sound ranges from harsh distortion to self-oscillation.
G-Force can be used with the following tubes:
ECC83 (Original ECC83S), 12AX7, 7025, ECC803, 6057, 5751, 6L13, B339, CV492, M8137, CV4004

Technical data / controls:
•Discrete vacuum tube bass amplifier, voltage controlled
•additional discrete source VCA, voltage controlled
•Feedback loop including limiter, can be switched on and off
•AC coupled inputs
•RC low-pass smoothed CV inputs to minimize click noise from square CV sequences
•Widely varying degree of saturation
•Feedback resonance waveform highly dependent on Bass EQ parameter
•Eurorack inputs 268 kOhm against GND /
Line level inputs 210 kOhm against GND /
Saturation inputs 230-480 kOhm against GND
Requirements
•Vacuum tubes are thermo-ionic devices; They require high temperatures to function, which means high power consumption. Tubes of this size require hundreds of milliamps momentarily at turn-on to start the heating elements - this means that your Eurorack system must supply large reserves of current when the module is switched on - in this case 175mA at +12V in continuous operation, and up to 350mA at +12V at switch-on pulse (approx: 0.5-1 sec) .
