About the MB185 III
The VTL MB185 III, formally the MB-185 Series III Signature Monoblock, is a fully balanced all-tube monoblock power amplifier from Vacuum Tube Logic. It uses a redesigned signal path, automatic biasing, fault sensing, and a user-adjustable damping factor control to tailor speaker matching and output impedance. The amplifier can operate in triode or tetrode mode and is designed for high-power tube performance with improved stability, lower noise, and better tube protection. It is a factory-upgradeable Series III platform and is offered in black or silver with rack-mountable, ventilated construction.
