SynergyII\Cu - LM3875 Gainclone

SynergyII\Cu started with 3.6kg of 100% very thick copper plate. The enclosure was selected, a 1U, 19" rack mount. The challenge was to build a pure Gainclone with its three resistors and simple 1500uF storage capacitors in a compact 1U enclosure. Everything had to fit in this tiny space including two 48VAC toroidal transformers for the dual mono supply, The LM3875 amplifier weighs 9.6 kg. The sound is clear, clean and solid with bass extended and very controlled.

See the original Synergy LM3875 Gainclone Amplifier (Chip Amp) project page.
