Significant 50Hz mains hum on lower FM frequencies around 90khz, hardly noticeable at 100khz or when using AUX INPUT.
Have not opened it up yet, but guess a power supply issue. Would appreciate any pointers.
This is an early model - don’t know whether it has IC smoothing as described in a You Tube post for a later model with CD player.
Are there any circuit diagrams available for this model?
Thanks
