These are the bare PCBs of an ultra high-end power amplifier. The power amplifier is with reference to Goldmund Mimesis 9.2 power amplifier.
The original product uses three pairs of lateral mosfet. We scaled up the amplifier by using 4 pairs of lateral mosfets to give more margin and better bass authenticity.
Original Product Specification :
Power output: 175 watts per channel into 8Ω (stereo)
Frequency response: 1Hz to 150kHz
Total harmonic distortion: 0.01%
Input sensitivity: 1.55V
Signal to noise ratio: 120dB
Speaker load impedance: 1Ω (minimum)
In our boards, we retained the feature of one board integrating power supply amplifier circuitry for lowest rail impedance as to attain high speed and stability performance.
Supply voltage : +/-65V to +/-80V
We provide schematic and part list by email
PCB dimension : 238mm x 120mm.
PCB thickness : 1.6mm
