    Power amplifiers stereo

    CH Precision A1.5

    The amplifier uses a powerful 1,700 VA transformer - it is housed in its own case, which is completely vibration-free and shielded. The power supply uses ESR capacitors, but they are not present in the signal circuit. The entire analog part of the device is assembled on discrete components. Feedback is configured from the front panel in increments of 20%.
