Biasing your amp - One thing you might need is a tech.

After installing your power tubes, more often than not, your amp will need to be biased (unless it is a non adjustable, fixed bias amp). If you are not familiar with biasing, and don't have much of a technical background, it may be better to get the job done by an amp tech. Otherwise, I have provided some links to get started on biasing.
