Product explanation ■ Version 2 of the vacuum tube radio was completed. This time, the vacuum tube made in China more than 30 years ago was used, but the performance was improved by changing the type.
In addition, you can also conduct sound amplification experiments with the newly included microphone unit.
Assembly takes approximately 2 hours.
By incorporating electronic components such as transformers and resistors, and making open-close type varicon and Litz wire antenna by hand, you can learn the basics of radio circuits and feel the role of vacuum tubes.
After assembly, please enjoy the unique nostalgic sound.
