Sometime ago, I've built-up a simple single-sided test brd where I could plug-in a TDA72xx series family power amp without a pre-amp. It works supremely. I advanced the design to include a front-end with or without a pre-amp. Under the same design, same configuration, following the same app note to the tee, the TDA7269A amp attempts to start up and immediately shuts down.
If anyone has any suggestions to try, I would be happy to try them.
Thanks,
Dave
