Quad FM4 Tuner / MP4480
 

I realise now that there has been many concerns about the Quad FM 4.

Can anyone help with my Quad FM 4 fault, maybe someone has the same problem.

The stations will not memorize. Manual tuning works but when the station number preset is selected together with tuning button no memorizing. It just goes to some random frequency readout? New IC1 replaced.
