ok so after installing a new 494 chip the amp will power up and seem to be fully functional but after I power the amp off and on for a 2nd time the chip is dead and the amp goes straight into protect
Ok so I got the amp up and running but there is a strange issue. When I power it up at first it starts up fine and plays audio but when I shut it off and power it up again it goes straight into protect and won't power up normally til the rail caps fully discharge.
It will only power up if the voltage is below 12.5v. anything above that and it goes into protect. Once its on it operates at 14.4v but will not power up at 14.4v.
When I power this amp up it works fine but when I remove the remote I get a pulse of about +20vdc on the drain of the low side preventing the output section from starting until the +20v goes away. Any ideas whats going on?
