SupTronics X400 v3.0 Raspberry Pi DAC & Amplifier - Faulty. Please note: This Raspberry Pi IS2 DAC/amplifier initially worked fine but then one of the chips burned out on turning on the power. There must have been a surge. As you can see from the photos, all the other chips/components look unaffected, so someone may be able to fix or use the other features/parts of the card. Can deliver or accept cash on collection.
