Question about Audio Players & Recorders
When switched on at the mains the power light comes on at the amp and the speakers make a loud crack. The power light is the only light on and the remote or manual controls only allow the amp to be turned on and off. You can't get anyting else to work.
If your speakers are making this noise on switch on please disconnect them and check out if they the speakers are damaged by a continuity test of the impedance. It must show the marked resistance without a short. Then you are lucky. Next open the amplifier and check out on the output side and the power side for failure of mains capacitors/ output drivers/faulty coupling capacitors. Connect a resistance loaded test- speakers whenyou do this test .Switch on and put the set on fopr voltage checks from the output to the preamp. By a signal test you will be able to analyse the gain factor of all teh corresponding stages.It might be possible that your amp is old and some electrolytics have dried up.If so put the amp on for some considerable time and confirm if there is response building up on the controls and panels slowly. If so check onthe board for the suspected passive components and replace all suspected capacitors. Also resolder the main pcb for bad connectivity. I am surre this must work but attampt only if your are familiar to doing this repair. Good day
