Hi everyone , my first post ! My out of warranty dac 9 got smoked due to a power surge , funny it was the only device in my rack that was damaged ,the transformer had a major meltdown , Nu prime was good enough to send a replacement transformer gratis but it got very hot right away so it was unplugged , so indicates a short on the dac board .Are these boards repairable? Replacement boards from Nu prime are almost $500.00 cdn landed so not worth it .Thanks for your time .
