Description
For sale is the amplifier in very good condition, fully functional and upgraded in three levels of improvement.
1) New electrolytic capacitors Cornell Dubilier 10000uf, Elna Sismic II, Panasonic ERF Nichicon FG,
2) Upgrade and replacement of all capacitors in the signal line from electrolytic to Wima MKS2 with much better characteristics.
3) Upgrade of the output amplifiers from 5532 (included) to OPA2134 with much better technical specifications.
With all the above improvements, the amplifier has achieved the maximum it could reach with significantly improved SNR (95db-->102db line) and THD (from 0.3 to 0.01%
Damping factor: 100
Input sensitivity: 0.25mV (MC), 2.5mV (MM), 150mV (line)
Signal to noise ratio: 102dB (line), 70dB (MC), 80dB (MM)
Speaker load impedance: 4Ω to 16Ω
Dimensions: 444 x 86 x 346mm
Weight: 7.2kg
