What happens when a tube amp fails?

I've been the very satisfied owner of a Yaqin MC-30L tube amplifier for the past few weeks and am wondering what to expect when a tube fails or something else fails? Is it going to just stop playing through one channel, start smoking, or start my house on fire?

Please give me some insight into the different types of failures and what the result is.

Thanks

I had a tube circuit go bad in an ARC CL-60.
I wasn't aware of it until I traded it in for a new VT-100 MK-I.
The store owner said a resistor burned out but, again,
it wasn't detectable sonically.
I did play at very conservative volumes so maybe this helped mask the problem.
This was one tube in a four-per-channel stereo amp.
