Here my first build I made about 10years ago. Based on a playmaster series 3, midget output stage. Has 10000uF caps, 35amp bridge rectifier, 500va toroidal transformer etc this is a class ab amp. This is just the amplifier enclosure, the pre-amp and buffer are separate units. Has worked flawlessly for a long time! Does get rather hit due to the size of the heatsink.
