Trogotronicm/277 Stereo Tube VCA + External PSU

Trogotronic m/277

For those looking to add rich tube harmonics to their Eurorack modular synthesizer setups, look no further. The Trogotronic m/277 is a high-gain Vacuum Tube Stereo VCA module that utilizes two discreet high-voltage VCA circuits to achieve deep compression, tube harmonics, and stereo imaging. The m/277 is a tactful means of adding analog warmth to cruel digital signals, or lending some stereo depth to an incoming mono signal.

Additionally, an incoming mono signal can be panned using the dedicated CV amplitude inputs—this works really well when combined with the module’s stereo overdrive effect (which also features its own dedicated per-channel CV input).
