TUBE 802

GENERAL DESCRIPTION


photo 802 Pentode — easy to drive — no neutralization — a favorite for crystal, oscillator and buffer/doubler stages.

The 802 is a pentode transmitting tube of the heater-cathode type for use as an r-f amplifier, frequency multiplier, oscillator, and suppressor-, grid-, or plate-modulated amplifier.

The plate connection is brought out through a separate seal at the top of the bulb to maintain low grid-plate capacitance.

Neutralization to prevent feedback is generally unnecessary in adequately shielded circuits.

The suppressor and the special internal shield are connected to individual base pins.

The 802 may be operated at maximum rated input at frequencies as high as 30 megacycles.
