What can be used instead of vacuum tubes?

discrete transistors
A transistor computer, now often called a second-generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable.

What replaced tubes in electronics?

The transistor, which essentially functions as a solid-state electronic switch, replaced the less-suitable vacuum tube.

Are vacuum tubes still manufactured?

Today, there are few factories left in the world that still manufacture vacuum tubes, a technology developed more than a century ago instrumental to early radio and the go-to method for amplification until the increased popularity of cheaper solid-state technology in the 1970s.

What is the difference between transistor and vacuum tubes?

Transistor and vacuum tube both are almost same in conceptually. Transistors are used in small integrated circuits which require low voltage supply and Vacuum tubes are used in high power applications. In the manner of size, the transistor is smaller than vacuum tubes. Vacuum tubes are really big and very hot.

What should I look for when buying a replacement tube?

tube, there are three things which must be observed: 1. Shunt resistors must be added to the 150 ma. tubes in the receiver so that the tube which is being used as a replacement can obtain its full 300 ma.

How do I select a substitute tube for a stage?

Tubes with the same base, and if possible the same basing, should be selected, as any disturbance to the original wiring might make it difficult, if not impossible, to realign the stage properly. Where the substitute tube has a different value of screen current a change in the series screen resistor may be required.

How do I search for tubes or valves?

You reach this tube or valve page from a search after clicking the “tubes” tab or by clicking a tube on a radio model page. You will find thousands of tubes or valves with interesting links. You even can look up radio models with a certain tube line up. [rmxtube-en]

What should I do if the substitute tube is not working?

Unusual operating conditions may require analysis. B. This means that the heater voltage on the substitute tube is different from the required type. In most cases this can be taken care of by changing or shorting out a section of the series resistor.
