Just let it thaw out before powering it up. Mine came from Chicago, over frozen Mountain passes and it sat in the studio for 2 days before I turned it on. Then I let it sit powered on for 4 hours before I loaded the reels on it. Everything seems fine, I haven't calibrated it yet, the meters are off on some channels, but no biggie for me right now, it records and plays back wondefully. ( Im always riding the tape return pre's anyhow)
