Always ensure that the speaker is connected to the amp – Based on their design, tube amplifiers want to see speakers connected at all times. When the speakers aren’t plugged, the amps usually blows the transformer which often costs between $200 and $300. To avoid this always make sure that you don’t manage a tube head or tube combo without plugging within the speaker.

Don’t obtain it wet – It is a good sense issue, but some people carry it as a given. Because of this most people have a tendency to leave drinks on the amp. For ideal results you need to never get the amp’s cover wet because it has a tendency to degrade the cover which ruins the resale value.
