Restoring a vintage radio receiver has the potential to be a fun weekend project, but it pays to know what you’re up against. Especially in the case of vacuum tube electronics, running down gremlins ...

PROF. L. B. ARGUIMBAU'S title is perhaps more suitable for one of those gloomy, but useful, volumes cataloguing every conceivable circuit in which valves have ever been used or misused, for he has ...

The project was created to supply the increasing demand for prototype vacuum tube circuits with additional features such as speakers, output transformers, and LEDs. The project was created to supply ...

Science keeps discovering new worlds and industry keeps conquering them—sometimes absorbing a few casualties in the process. After the transistor was invented, it caused trouble for many vacuum-tube ...

Vacuum tubeIs an electronic component that performs signal amplification, detection, rectification, etc. with an electrode enclosed in a glass or metal tube whose inside is evacuated. Until a ...

If you work on simple digital projects, just about any bench supply will offer the voltage and current you’re looking for. However, if you’re working with valves, you’ll often find yourself needing ...
