DC filament supply for Bottlehead Kaiju 300B amplifier
The Kaiju DC filament supply upgrade is a regulated DC supply conversion for the AC heated 300B filaments of the stock Bottlehead Kaiju 300B amplifier. There is a separate DC supply for each 300B, composed of low voltage drop Schottky rectifiers, a CLC filter using a common mode choke, and a low noise regulator optimized for fast transient response.
This supply will reduce the already exceptionally low noise floor of the AC heated Kaiju 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 a black background between the notes or in quiet passages of music.
This kit is mostly constructed on a printed circuit board. Experienced builders can expect to complete the upgrade in an evening or two (but take your time!).
