Just wondering if it is fairly typical for the 252MO power supply to have an 
audible hum while idling. I just picked up a used one
and finally used it for a full day and noticed the hum when the house finally 
went quiet and I plugged headphones in. The other part
is that when I advance the drive to where it just lights up the ALC (with ALC 
at max) the hum in the muted audio is significant. I
don't know how accurate the ammeter is but in this condition it shows about 20 
amps. I didn't get around to putting a meter on it to
check voltage yet. I would appreciate any info anyone may have after using one 
of these past or present. TIA.
