I have an M1a that is draining the battery between gigs. I thought it should turn itself off when unplugged. Has anyone experienced this?

I've seen this happen a handful of times. Generally, if the output harness develops a short in the jack, the battery will remain on at all times. If your M1A is under warranty, you can get that output harness replaced for free.
