Palladom start life as a Turbo F5 build for another. But after some months he was not happy with the sound and offered to sell back the enclosure and PS. The PS is extreme with 2X 300VA double secondary windings trannies, 16X 15A double diode bridges all with heatsinks and 192,000uf of capacitance. The only part I had to replace were the amp boards. I used the DIYAudio F5 boards with Dale resistors and matched FET pairs.
Easy to see the PS in a 5U enclosure is way over-speced. Fortunately it produced an extremely good sounding example of a high-performance F5. Being able to push the current up this amp will produce 32Watts of Class A and about 50W of Class B. In the image above the yellow alligator leads were used temporarily to establish the right earthing setup. Because there is so much heatsink area the amp gets just warm. Very heavy though and now sold.
