hi

i have a new properly operating ie not deffective astron (analog) power
supply

naturally even w/no load the transformer makes a bit of a buzz the
usual kind


how do you quite that?

i've seen some transformers in the past completely covered w/metal not
sure if buying such a replacement is practical or if that would 'do ' it

further i presume the transf would get hotter and need additional
cooling ? (astron has no fan)


any tips ?


tnx
