The model is made according to a push-pull scheme, and each channel has a pair of powerful KT150 lamps, providing a solid output power. The drivers are familiar to the company's 6H30 products. The amplifier is encased in a solid aluminum chassis, and GhostMeters branded arrow indicators are displayed on the transparent front panel. On the back panel there are unbalanced and balanced inputs, as well as separate terminals for connecting speaker systems with a resistance of 4-8-16 ohms.
