Tube-based Power Supply

The Dual Regulated Power Supply (Dual Power / DRPS) is an external, fully tube-based power supply engineered to maximize the performance of the Control B Evolution preamplifier. Designed around vacuum-tube rectification and active tube regulation, it delivers exceptionally stable high-voltage supply independent of mains fluctuations, significantly reducing hum, ripple, and noise. By isolating the power supply from the audio circuitry and using regulation stages based on rectifier, error-amplifier, and ballast tubes, the Dual Power ensures consistent operating conditions for the preamplifier, resulting in improved transparency, dynamics, and overall musical coherence.
