Installation And Application

The base pins of the 830-B fit the standard 4-contact socket, such as the RCA type UR-Ï42A. The socket should be mounted to hold the tube in a vertical position with base down. The plate lead is brought out to the cap at the top of the bulb.

The plate of the 830-B shows only a barely perceptible red color at the maximum plate-dissipation rating for each class of service.

For high-frequency operation above 15 megacycles, see page 144.

For additional information, see chapters on INSTALLATION and APPLICATION.
