Question about RCA RS2640 CD Shelf System
I had the same problem with mine and the fix for it was to replace the Q401 transistor on the main board. Used a NTE382
replacement and it has worked fine.

Sorry you feel that way David. they may have asked you that question so the buzzing can be isolated. If the buzzing DOES go away when you mute the unit, that means that your problem is in the preamp circuit of this unit and not in the audio output stage circuits. The only problem with these shelf type stereos, is the cost to repair. As most of the time, the part and labor cost exceeds the cost to replace, but you can certainly make up your own mind on this matter. If you feel this unit is worth it to you to repair, go for the repair! Good Luck with this repair.
