Tubes generally last 1-2 years depending on how often/loud you play. This is just getting out of hand. Amp manufacturers such as Marshall and Fender have always recommended replacing power valves after about two years if you’re regularly playing at concert volumes.
Why does my amp get really hot?
What are the problems when an amplifier gets too hot? There are several different reasons that an amplifier will get hot and shut down. Four of the most common are: Blown/grounded speaker(s), poor power and/or ground connections, too low an impedance (load), or Gain/Punch Bass control settings too high.
How long does a 12ax7 tube last?
about 10,000 hoursSmall signal tubes like a 12AX7 or 6922 will work well on average for about 10,000 hours. If you leave your equipment on 24 hours a day, well you do the math: There are 8,760 hours in a year.
How long should you let a tube amp cool down?
3 minutesWhen powering off, the tube generally needs 2 – 3 minutes to cool down.
How do I know when my tubes need replacing?
A: These are the most common signs that tubes need replacement: Excessive noise (hiss, hum) including squealing or microphonic tubes. Loss of high end. … A muddy bottom end; Sounds like there is too much bass and note clarity is lost. Erratic changes in the overall volume. … The amp doesn’t work!
Is it bad to leave an amplifier on?
Leaving it on will use power, which can be considered bad form environmentally and cost you a bit on the power bill. Leaving it on could eventually cause it to fail somewhat sooner than it might otherwise have.
Can you touch vacuum tubes?
Think of a vacuum tube as a light bulb. It is a glass envelope that generates heat as it is working. You shouldn’t be handling them all the time but occasionally touching them will not hurt. Let it cool off first though, they can get mighty toasty.
How do you break in new tubes?
In the past I used to break in tubes in a relatively fast way by leaving the Phono preamp on for 2 or 3 hours and then off for an hour to let them cool down and then on again for another two or three hours and start again during the whole day, taking note the amount of hours the tubes have been actually working, …
Do preamp tubes need to break in?
Yes, they do break in. Do they NEED a break in? Not really. Small signal tubes especially will sound good within a few minutes of warming up but they will tend to sound better after a while because everything gets “baked” and molded into shape so to speak.
Is it normal for tube amps to get hot?
As everyone one has stated it is normal for tube amps to get hot. If you’re really worried about it though purchase a small fan to keep things cool. Tubes do get very very hot, they’re essentially overpowered lightbulbs (Take that term very loosely you techies out there) so it should be fine.
How much does it cost to replace tubes in an amp?

Do tube amps sound better?
Tubes sound better because their distortion products are more musical. Tubes provide a more appropriate load to transducers. Those are the fundamental reasons why tubes simply sound better. Tubes are voltage amplifiers as opposed to transistors which are current amplification devices.
What happens if you don’t bias a tube amp?
If you changed to tubes with a lower resistance without biasing the amp you would quickly burn through those tubes and potentially damage the amp and yourself in the process. This is because the amp is still pushing out current at a higher level than the valves are able to take. Until it’s been correctly re-biased.
