This document provides critical specifications, operating characteristics, and application notes necessary for designing and operating circuits that incorporate this classic tube. Whether you’re a seasoned ham radio operator, a vintage audio enthusiast, or a student exploring the world of electronics, the 813 Datasheet is an indispensable resource.
Deciphering the 813 Datasheet
The 813 Datasheet is essentially a comprehensive technical manual for the 813 vacuum tube. It outlines everything from the tube’s physical dimensions and pinout to its maximum voltage and current ratings. Understanding this information is crucial for ensuring the safe and efficient operation of any circuit employing the 813. Datasheets typically include absolute maximum ratings, which are the limits beyond which the tube may be damaged, as well as typical operating conditions, which provide guidelines for achieving desired performance.
Datasheets are vital for designing amplifiers, oscillators, and other circuits that utilize vacuum tubes. They provide the necessary data to calculate component values, predict circuit performance, and troubleshoot potential problems. For instance, the 813 Datasheet will specify the recommended plate voltage, screen voltage, and grid bias voltage for different operating classes (e.g., Class A, Class AB, Class B, Class C). Understanding these operating points is essential for achieving optimal power output, linearity, and efficiency.
Here’s a simplified overview of the kind of information you might find represented in a datasheet:
- **Tube Type:** 813
- **Filament Voltage:** Usually 10V
- **Maximum Plate Voltage:** Varies depending on operating class, but can be very high.
A datasheet also helps with determining things such as:
- Pin Connections
- Typical Operation (Specific Voltage and Current)
- Transfer Characteristics
| Parameter | Value | Unit |
|---|---|---|
| Plate Dissipation | 125 | Watts |
| Grid-Screen Dissipation | 15 | Watts |
