megael9 · 11th October 2011, 10:05 PM

This unit goes to protection (sat) between 3 to 6 hour after
power on. no leakage or shortage transistors, any suggestion?

Is it going into thermal protection?

megael9 · 12th October 2011, 02:54 AM

don`t think so, because I shorted the thermistor
and same thin.

Perry Babin · 12th October 2011, 03:09 AM

When it shuts down, does the power supply shut down or do you simply lose audio?

megael9 · 15th October 2011, 02:57 PM

I let this amp play for over 15 hour at
50 % Of its volume and no problem,
but when Go more than 75 % volume
it goes into Aux mode.

What is aux mode?

Sorry, I ment sat mode.
About the battery, I should
I look for?

Look at the voltage your battery is displaying when the amp cuts out-your power supply may be sagging and causing the amp to shut down.
