TubePad 6.0 Tube Chart

Quick Reference Data

Name: 807
Use:
Heater-cathode tube type used as AF power amplifier and modulator and as RF power amplifier and oscillator. May be used with full input up to 60 MHz. For class C telegraphy operation at 80 MHz, plate voltage and input should be reduced to 80 % of maximum ratings; at 125 MHz to 55 %. Class C telegraphy maximum plate dissapation, CCS 25 Watts, ICAS 30 Watts.
Notes: Requires a small 5-pin socket and may be operated in any position. This tube is a true pentode (as is shown in the RCA TT-5 Tube Manual), not a tetrode, as is commonly described.
