SSE mod
want to have-build in USB DAC, (use to be installed inside PA CASE), is it ok to use secondary winding of power transformer (5 VAC5/5AR4 filament) as a source for DAC power supply.
Another question how to organize grounding to avoid loops, 2 PCB for DAC with 5V power, USB input, L-GND-GND-R output.
