About the ST150

The VTL ST-150 is a stereo tube power amplifier designed for high output, musical clarity, and strong bass performance in a relatively compact chassis. VTL describes it as an over-150-watt-per-channel amplifier with a high-energy storage power supply, proprietary output transformers, low-noise grounding, and switchable tetrode/triode operation. It is suited to smaller electrostatic panels and dynamic speakers that do not require very high current, and in triode mode VTL recommends speakers of 92 dB/1W/1m sensitivity or higher.
