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 ...

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 ...

Linear, small-signal AC models can be useful in the analysis and design of vacuum-tube-based circuits. Under large-signal conditions, nonlinear models are typically required. Almost 120 years ago, ...

It was a cold January Saturday night in Chicago and we had big plans. Buddy Guy’s Legends bar was packed. We setup directly under one of the PA speakers less than 15′ from the stage. Time to celebrate ...

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 ...
