- Step 8: Final Assembly.
What does a vacuum tube do?
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
What are the parts used to build this radio?
Here’s a list of the parts used to build this radio. While most components are common, some are hard to find these days (the tube, variable capacitor and high impedance headphones/output transformer), so I’ll include more information about those in later steps.
Is there a vintage contest for tube radios?
*** This is my entry in the Vintage Contest. When I read of the contest sponsored by Crosley, the first thing I thought of was tube radios. I’ve wanted to try building a tube radio for a while, so here’s an instructable on how I did it. If you like it, please don’t forget to vote for me in the Vintage Contest. ***
How do I choose a tube?
When selecting a tube it’s important to keep in mind the required filament/heater voltage and current, as you’ll have to make up a battery to provide the required voltage. Most American tubes start with a number indicating the voltage (6. 3 volts for the 6 JC8 and 6 U8). 6V and 12V at around 0. 3 – 0.
What is a triode and pentode tube radio?
The radio is a regenerative receiver using a combination triode-pentode tube (which is like having two tubes in one, so I guess this is actually a two tube radio?). The triode section is used in an Armstrong regenerative detector and the pentode section is used as an audio amplifier.
