yipes..
It's been plugged in for a year and a half. The AC adapter died.
The exact replacement costs $50..no way..
I purchased a 3v / 1.7A Camera AC adapter off of EBAY and just changed the connector, this was $15 with shipping. Works just fine.
New rule, don't keep the AC Adapter plugged in for a year and a half. Plug it in when I need to use the recorder.
