Audiophile Power Amplifier

Nice implementation of the well proven Jaycar KC5201 Kit modules. Extremely solid power supply with a big toroid and overkill 6 x 6000mfd smoothing capacitors. I measured 186 watts into 8 ohms both channels driven. Massive headroom for the right source and speakers.

The gain of this one has been set to .7V rms for full power. Can be driven direct from a cd player or ipod/tablet etc. Has a stereo gain/volume control on the hardwood front panel. The rest of the chassis is aluminium. Premium gold parts have been used for the input RCA's and the output binding posts.

Can also be driven from a preamp, smart tv, computer, mixer, DAC, bluetooth box, chromecast etc. This kind of performance normally costs thousands of dollars, yours for pocket money.

125 watts (very conservative) .03% distortion
