Yamaha EMX512SC power supply repair
Schematic on page 140: https://elektrotanya.com/yamaha_emx512sc-emx312sc.pdf/download.html
It blowed some resistors, R418 and R458. Any ideas of what could be happening?
I had already fixed this problem before, I replaced both R418 and R424 and it was working fine. this time blowed R458 too. there is no other visible damage or weird voltages.
