The absolute truth about Radio Repair! Most of the customers do not realize that a device is repaired fast because of the inbuilt expertise! Customers do not question or hesitate to pay a doctor's fees, but expect free service from us as though they are doing us a favour by coming to us! Majority do not understand that the expertise achieved is out of toils and burning a lot of night oils! What to do! Many thanks for your interesting comments, dear!

The radios that I used to enjoyed most to repair were the ones with the IC 2822. The IC has only 8 legs and I knew offhead the functions of the legs/pins and that made troubleshooting easy. However on a good day I would repair a radio so fast and that would make a customer fail to understand why any payment should be made at all, you know most radio and phones customers stay arround watching as you make repairs. All the same, radio repair comes with sweet memories !

Only one end of the pot goes to the IC. The other end is grounded. When I grounded both pins, it becomes a variable resistor, which was enough for volume control in this IC. The ground potential is combined using both pins, that's all. In all probability, the pin that controls volume in the IC must be an audio signal out from the preamp that is connected to the amp section inside. Hope I am clear enough. Many thanks for your keen observation and expert comments.

Very nice radio repair and maintenance article Parasuraman. Although the explanation about the shorted centre pin with the hot pin that solved the crackling noises still leaves a question mark after reading?
With the following text that the volume is controlled inside the IC which does not affect the low-high variation?
