Can you put any tubes in a tube amp?

With power tubes, you can swap different brands of the same tube. (For example, 6L6 tubes from different manufacturers.) But do not swap different types of power tubes unless you are absolutely sure you know what you are doing — damage may result.

Where is the Peavey Classic 30 made?

Made in USA. Includes 2 button footswitch and power cord.

How do I know if my amp tubes are bad?

Sometimes you will hear strange sounds, loss of power, or heavily distort sound. These are signs that a tube is failing. Often power loss that seems like the amp is performing at half power or less will be one or more bad power tubes, or even a dying phase inverter tube.

How can you tell if a vacuum tube is bad?

When a vacuum tube develops an air leak (a small crack or bad seal by a pin for example) this getter color will change to pure white. If you see this you know with 100% certainty that the tube is bad. Third, look for a purple glow that is very focused around specific elements inside the tube.

Are 12AX7 and 12AT7 interchangeable?

You can interchange a 12AX7 with 12AT7, 12AU7, 12AY7 or 5751 as they are all the same pin structure, however they will each give you a different result in your amp. Each of these tubes has a different gain factor, which means some will give higher gain and others lower gain.

Do 12AX7 tubes need to be matched?

Using 12AX7s as an example, matching these preamp tubes is a good idea, but by no means essential. These tubes, along with the 6DJ8 variety, are known as linestage tubes. When they are matched, this will ensure that you get even gain from both tubes.
