NAD 7150 FM section

audiofan · 30th December 2009, 02:45 AM

I have a NAD 7150 The multiplex use a HA12016 Hitachi 16 pin chip.
Unfortunatly the stereo balance is most of the time off balance, I did a few measure but find nothing ( voltage are normal ).
Should I change the chip ? Does anybody have some experience with this type of circuit or problem ?

Does the imbalance exist on all the stations you can receive? I would try aligning the FM receiver before replacing anything. The procedure is in the service manual.
