Hi!
I've made 10 LM3875 GC and all of them have the same problems:
1- 250mV DC at output with load and 300mV DC without load.
2- When I turn off the power and after the caps discharge (10.000uF / rail) I have no 'bump' but a sweep at high frequencies (puiiiii).
Only 5 of them are connected at the same time (AV amp). I've tryed one at each time, and the result is the same.
Is this normal??
I have the attached config
Regards
Pedro Martins

That's it.
1k resistors should do the job.
