There are some general practices that can help get the most out of your tubes such as:
- Be sure to allow the tubes time to warm up before you start really pushing them.
- Anytime you're not using the amp, it should either be off or in standby. Try to avoid leaving the amp on for extended periods of time but don't turn it off and on if you're going to be playing it. Rapidly cooling and heating the tubes can shorten the lifespan.
Beyond that, the more you play - the shorter the lifespan will be and the quicker you will need to replace them.
