1624
Beam Power Pentode

EIA Base & Outline

EIA Base: 1624EIA Bulb: 16-2
Source ........................................ RCA TT-5 - 1962

Application

Coated-filament type as rf power amplifier and oscillator. May be used with full input to 60 MHz. For operation at 80 MHz,

plate voltage and plate input should be reduced to 80 per cent of maximum ratings; at 125 MHz, to 55 per cent. Requires small 5-contact socket and may be operated in vertical position only, base up or down.
