Stereomour II DC filament supply

The Stereomour II DC filament supply upgrade is a DC supply conversion for the AC heated 2A3 filaments of the stock Stereomour II amplifier. There is a separate DC supply for each 2A3, composed of low voltage drop Schottky rectifiers, a CLC filter using a common mode choke. This supply will reduce the already exceptionally low noise floor of the AC heated Stereomour II amplifier to levels acceptable for use with the most sensitive horn speakers. Its installation is recommended in particular for use with speakers above 96dB@1W@1M sensitivity. It may also be useful in systems employing speakers with a lower sensitivity, enhancing the sense of “black background between the notes” in quiet passages of music.

Please note that this upgrade is only to be installed in the Stereomour II. The original Stereomour uses a different power transformer that is not compatible with this upgrade.
