Is this the same op-amp that senses absolute low voltage and tells the Empeg to write to flash and shut off? I am the guy that had that weird broken resistor problem that did not let my Empeg save on power down. I was losing all my settings when power was removed because that op-amp circuit did not work correctly and was not able to signal the processor upon power loss. This problem seems to me more code related, does the Empeg read battery voltage through an A/D anywhere? I thought the low battery icon was activated in the 10V - 11V range through software? My battery is not the greatest but I know I am well above the 8V range with the key on, probably in the 11V range. I will hook it up to a lab supply tonight and figure out the exact voltage where this "icon" condition occurs.
