Do they still make vacuum tubes? Yes! Vacuum tubes are still used in applications where high power is required. And that's because there are no solid state (semiconductor) devices that can deliver what a hefty vacuum tube can produce. We see vacuum tubes used in the broadcast transmitters that radio and TV stations send out their signals with. We also see vacuum tubes used in radar applications, and in things like X-ray generation. You want big power? Get a vacuum tube to deliver it. As we move up the power scale, we'll see solid state devices falling off the truck until we're left with just vacuum tubes. There's a bit more.
Now that newer technology has appeared and is becoming more common, the cathode ray tube (CRT) in "regular" television sets is disappearing. (The CRT is a vacuum tube.) There are still plenty of these "older" units being used and marketed in other parts of the world. But the chances are excellent that you encounter a device using a vacuum tube at least daily. The tube we're talking about is called a magnetron, and it is the vacuum tube (a diode with associated magnets that works as a cavity resonator) which generates the microwaves energy that is used in microwave ovens.
Vacuum tubes were developed and advanced long before solid state devices came into being. But, though semiconductor technology is at the heart of almost all electronic equipment around us today, the vacuum tube still does the jobs that solid state devices cannot manage. And this will continue to be the case for some time to come.

What are the uses of vacuum tubes?
to make stoves......its easy
Why are vacuum tubes still used?
Because they have qualities that make them attractive. In audio technology, a vacuum tube amplifier sounds softer and richer than transistor amplifiers to many listeners.
What other devices use vacuum tubes?
Vacuum tubes still find uses where solid-state devices have not been developed, are impractical, or where a tube has superior performance, as with some devices in professional audio and high-power radio transmitters. Tubes are still produced for such applications.
Do todays computers use vacuum tubes?
No, unless you are still using a CRT monitor.
How many vacuum tubes are in the Univac I computer?
It used 5200 vacuum tubes.
Who buys vacuum tubes?
Vacuum tubes (especially triodes, tetrodes, and pentodes) are still the most popular form of amplification in guitar amplifiers, because of their unique tonal characteristics, and the distortion they produce when pushed past their limits. Vacuum tubes have a lifespan, so they are needed to fix tube amps.
Do all vacuum tubes light up?
No, there are some cold cathode vacuum tubes. These do not light.
Where is a good place near Seattle where you can buy old vacuum tubes?
This would depend on the type of vacuum tubes needed. Any car part store will carry vacuum tubes for a car, general stores carry vacuum tubes for household vacuums, and AC part stores will carry vacuum tubes for the AC/Heating system of a house.?æ
Where was vacuum tube was made?
who made the vacuum tubes
How many vacuum tubes in first generation computer?
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.
Can a dicconnected vacuum tubes cause the engine to run badly?
yes they were put on there for a reason ,,a vacuum leak will make a car run terrible.
What household objects have a vacuum in?
the cathode ray tube in an older TV or monitor. valves (vacuum tubes) in older radios or stereos. some stereos and record players are still made with for those who wish. Fluorescent tubes and incandescent bulbs are made with a low pressure not quite a vacuum.
