The ES9038Pro DAC Nightmare (Did My Dedicated Oscillator Mod Kill my DAC? NLOCK)

[audio.bill]

I can't help you determine exactly what caused the problem you're experiencing or whether the DAC's operation can be restored, but connecting a transformer to a power supply input which draws less current than the capacity of the transformer is not a problem and should not have caused any issues. The circuit will only draw the amount of current it needs from a transformer with higher current capacity. For example consider an isolation transformer used for AC power which may have a capacity of 15A, they're commonly connected to components which draw a total current less than the 15A rating. You'll only run into a problem (and often blow a fuse if so protected) when you try to draw more current than the transformer is capable of providing.
