4. Erratic changes in the overall volume.
5. The amp doesn’t work!

Can I change tubes without biasing?

Some amps will never need to be biased because they come out of the factory at a fixed bias like Mesa/Boogie amps. If you changed to tubes with a lower resistance without biasing the amp you would quickly burn through those tubes and potentially damage the amp and yourself in the process.
