Hello
on my amp spider IV 75, the power amp TDA7293 smoke when I turn on the power. I can hear a little boom in the speaker the the TDA blows and smell.
I replaced the TDA component by it happen again
all the logic, master board and pre-amp stage seems to be working. If I plug my phone playing music in the MP3 entry and an audio headset in the external jack, I can hear the music, and master volume control also works in this case
any idea on what happens?
the amp is out of warranty, and pretty old so a repair done by a service center is not a reasonable economic solution
finding the wiring schematics of the amp would help if anyone could provide it?
Thanks in advance for your advices
