That will depend HOW it fails to meet Class B -- and who it affects.  It's
not unusual to find switch mode PS's that meet Class B above 500 KHz or 1
Mhz -- and fail it at, say, 100 or 200 KHz and lower.    Would it create
harmful interference? A radio might not work well near AC power when it's
plugged in. Have you checked?  An AM and SW broadcast portable is good for
this. _Would_ anyone beside yourself be affected?
