I am working on a TDA7294 outputted with a 2SC5200 and 2SA1943 pair....The design seems to be very popular and I got it from a website called 320volt.com. After making the PCB successfully, I tested it on a PC SMPS but mistakingly connected 0 volt and negative and this led to a lot of heating mainly in IC and too some extent in the BJTs. Afterwards, I connected it properly and everything went smooth....I was able to hear the sound... No problem with heatsinks...
Yesterday, I made a dual rail supply of 30-0-30 volt and connected it to the amp. I used filters and all..made the connections proper....but the IC blew up.....
What could be the reason ?????
