And that was a smart thing to do as the first stages have the highest gain and are therefore the most sensitive.
I also see that trick in many today's high end amps.
Not just that, they sometimes put the rectified and filtered voltages through a Linear regulator / LDO, which all but eliminates any ripple. That makes it super-quiet.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
