Summit Audio TPA-200B

The Summit Audio TPA-200B Dual Tube Preamplifier combines the best of two worlds: vacuum tubes and high quality solid state. This unique combination creates an environment that yields the warmth associated with tubes without the inherent high frequency loss while providing the reliability of solid state components. The TPA-200B is designed to work in a variety of applications using three input types: microphone input, line level input, and front panel Hi-Z input.
