Designed for control room use, the VT-275HF is a stereo power amplifier specifically geared to the needs of producers and engineers requiring the utmost in fidelity. The all-tube design is low in distortion and features high quality audio components and transformers for ultra-linear output and fatigue-free listening.
The VT-275HF features 75 watts per channel into 2, 4, or 8 ohms and high fidelity, bifiler output transformers. The unit has three preamp tubes, two 12AT7a and a single 12AX7a, while the output has four Svetlana 6550c tubes. The preamp tubes are supplied with fully regulated 350V high voltage. The amplifier has independent volume controls for each channel, a toroidal transformer, and is housed in a rugged steel rack-mount chassis.
