How long do radio vacuum tubes last?
Tubes don’t just “quit” suddenly. They lose their drive capability gradually with use. Small 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.
What transformer is fixed in a radio?

Why are vacuum tubes so expensive?
Tube amps are expensive because they adopt pre and power tubes as their primary amplification source. Each tube costs roughly $50 and can have up to 4 of them within a single unit. Secondly, these amps have more expensive components, larger cases, and more complex circuitry than solid-state amps.
How do I know if my vacuum tube is bad?
