Hi,
Have a SMPS with pulsating buzz sound when it is in standby mode, frequency of the pulsating buzz is about 1 hz. The buzz is comming from the secondary part near the output voltages. When I power up the instrument from standby, it is away (?) but not 100% sure, there are fans running and could be there but I can not hear it. However, the SMPS works fine. What can that be ?
Thanks
