Personally, i would not leave a tube amp on without having some type of terminating load on it. If you want to do something like this, go to Radio Shack and pick up a pair of 8 ohm or 16 ohm resistors. You can connect these across the speaker terminals like they were speakers. Check them after the amp has been on for a short period of time to see if they are hot. If they are hot, shut down the amp. The amp may be oscillating from not having anything on the input.
If you use common sense, you'll be fine and it won't cost you more than a very few dollars to do what you want to do. Sean
