What is a Tube?
A vacuum tube, electron tube, valve or tube is a device that controls electric current
flow in a high vacuum between electrodes to which an electric potential difference has been applied.
What is the difference between a transistor and an electronic tube?Vacuum tubes require high voltage power supplies.
Transistors require low voltage power supplies.
As vacuum tubes use glass tube, hence their mechanical strength is less.
Transistors are mechanically stronger than vacuum tubes.
Farnsworth Electronics has hundreds of NOS tubes!
Does Grandpa's radio need a replacement tube? We might just have what you need.
We also have tube testing available. We also carry tube sockets.
