![]() If the caps in the can were to develop a short circuit, the surge of current could destroy that transformer. Those should be replaced with individual capacitors. Looking down on the top of the chassis, 2nd pic, the power supply electrolytic capacitors are in the metal cylinder next to the large black power transformer. This unit is old enough so that the electrolytic caps (at least) probably should be replaced but that should be secondary to determining and fixing the primary cause of the failure. Repair parts can be purchased on-line from vendors such as Mouser (also, check the ads in the right page margin). With these two items, and a little patience, you should be able to determine what is the actual problem with your set. Rather than engage in willy-nilly replacement of parts, you might want to invest in a Sams folder for this unit and a decent digital multimeter. ![]() You may have a bridge rectifier that has partially failed. If both left and right channels are suffering from low volume, I would look for a "common denominator" that affects both channels: that would be the power supply. It's not practical to "test" installed capacitors and for the work involved in isolating them and the cost of a cap tester, it's more practical just to replace them.īut caps may not be the immediate root of your problem. ![]()
