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 circuit was designed to create a power amplifier circuit that will utilize E80CC and EL34 vacuum tubes for better results while providing 35 Watts of power. E80CC – a special quality double triode ...

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 ...

The circuit was designed to create a line preamplifier by acquiring the use of double triode tubes. The circuit comprises of three parts, the main preamplifier circuit with tubes, the input selector ...

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 ...

The transistor revolutionized the world and made the abundant computing we now rely on a possibility, but before the transistor, there was the vacuum tube. Large, hot, power hungry, and prone to ...

Software Defined Radio (SDR) is the big thing these days, and why not? A single computer can get rid of a room full of boat anchors, and give you better signal discrimination than all but the best kit ...
