I have a Ray-O-Vac RY22 tube. So yes, a company sold tubes under the Ray-O-Vac name. I don't know if this is the same company that makes batteries or who actually made the tube. A Google search didn't find anything and Tube Lore doesn't list Ray-O-Vac.
I also don't know much about this tube. It isn't an "industry standard" 22 since it is indirectly heated and has a 5 pin base. It looks like an old 24 with the S (globe or balloon) envelope.
What else can I help you with?
How many vacuum tubes are in the Univac I computer?
It used 5200 vacuum tubes.
What generation was vacuum tubes used?
first generation computers
Why transistor is so necessary?
Without the transistor you would need vacuum tubes to accomplish the same thing. None of our inexpensive portable electronics would be possible using vacuum tubes.
Size of vacuum tubes?
Vacuum tubes have been built in sizes as small as the eraser on the end of your pencil to as big as a bus. It all depends on the purpose and power requirements. The typical vacuum tube used in household radios and TVs was half an inch to one inch in diameter and two to five inches tall.
Which is better a vacuum tube or a micro chip?
It depends on the application. Vacuum tubes work better under certain operating conditions and frequencies. The problem with vacuum tubes is they are not as easy to mass produce as semiconductor devices, and semiconductor devices such as integrated circuits can have litterally thousands or millions of transistors and other components on a single chip. Such scaling is not possible with vacuum tubes, though there is some research in the MEMS (Micro Electro Mechanical) field to suggest that micro scale vacuum tubes could be mass produced within an integrated circuit. Such applications could be useful in the Terahertz frequencies. When a lowcost and compact solution is preferred generally the silicon based microchips will be the best option.
How many vacuum tubes are in the Univac I computer?
It used 5200 vacuum tubes.
Do all vacuum tubes light up?
No, there are some cold cathode vacuum tubes. These do not light.
Where was vacuum tube was made?
who made the vacuum tubes
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
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.
What technology replaced vacuum tubes in the second generation?
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
Why modern devices use integrated circuit instead of vacuum tubes?
Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes less energy and are more reliable than vacuum tubes.
Vacuum tubes generation?
first
What has the author Karl R Spangenberg written?
Karl R. Spangenberg has written: 'Vacuum tubes' -- subject(s): Vacuum-tubes
What is vacuum tubes define?
Vacuum tubes are electronic devices that control the flow of electrons in a vacuum. They were widely used in early computer and radio technology before being replaced by transistors. Vacuum tubes can amplify signals and are known for their warm, vintage sound in audio equipment.
Who is the first generation of computers?
vacuum tubes
How many vacuum tubes were in the Mark IV?
The Harvard Mark IV had about 4000 tubes.
