It started with some relay cutoffs while playing music.
A week ago it took about 5-90 minutes for the protection relay to release.
Im in need of ideas and suggestions what to do.
Channel A heatsink get´s around 40 Celsius and channel B stays cool.
I have measured the powerbank and it delivers enough juice.
One odd thing i have noticed with the cutoff relay is that both poles on the coil got a positive 30V while the protection indicator is on.
I have compared the transistors from cannel A and B and could not find any anomalies.
