How can do you extend the life of your tubes?

onemug, I too wait to power up my amp again after a listening session. At least one hour, but I try not to power down until the music is over for the day. Cannot always do, of course, but that practice is in my listening choreography.

I was under the impression vacuum tubes were akin to light bulbs so they shouldn't be on all the time. I keep my tube gear turned off and only turn them on when needed. My warm-up time is similar to Pops.

One thing I'm trying to help prolong tube life are various tube coolers and dampers. I'm new to tubes so I'm not sure this stuff will help. On my preamp tubes I've got Herbie's tube dampers. On my power tubes I have Pearl PCF tube coolers. They look like heat sink jacket when put around the tubes. They supposedly help with the heat. I just started with them so don't know yet if they are truly helping. This will be a long term test.

Jedinite24, tubes are similar to light bulbs in that in rush current is their main enemy. You will notice that most light bulbs blow out when turning on a light, that's in rush current.

Tubes will last longer if you avoid turning them on/off. Certainly some previous advice is solid. Do not leave tube amps on 24/7 unattended, and you can use stand by circuitry if your tube equipment employs it.

Preamp tubes last for years,as a matter of fact I have antique radios that are over seventy years old with the original tubes and they are fine. Power amp tubes are more apt to wear out so I would not keep them on. Don't worry about it just enjoy it.

I use all tube equipment, amp and pre. I listen to music on the weekends. So i put on pre-amp on Friday leave it on till Sunday night. The amp stays on only when listening, then off she goes.
