LM4780 amplifier




My LM4780 amplifier, with Audiosector PCBs in parallel configuration.
Premium components (Caddock, Kiwame, Mills, Riken, Audio Note, Elna Silmic II, Nichicon Gold Tune, MKP-1837).
400VA, 2x26.5V transformer, snubberized PSU, zobel, speaker protection circuits.
Approx. 2 x 120 watts in 4 ohm.
12 volt trigger-on circuit (power on/off from pre-amplifier).
Thanks to Peter Daniel for his support. Thanks to Max Jens Jensen for the 12 volt trigger circuit.
Very satisfied with the sound.
