Receiving and Amplifying Tubes

Receiving and amplifying tubes are indexed by complete designation, execution and equipment function. A shared family prefix or similar envelope does not establish interchangeability.

Device types and operating roles

This section covers vacuum diodes, triodes, tetrodes, pentodes, combined tubes and rectifiers used for amplification, detection, frequency conversion, rectification and switching.

Operating data determine the execution

Heater data, pinout, electrode limits, gain, capacitance, base and operating circuit determine the required execution.

• record the complete marking and suffix;
• identify the equipment and circuit position;
• check electrical and thermal operating data;
• attach marking and interface photographs;
• state quantity and required documents.
