This can give rise to excessive screen grid current.

More than one screen grid can be used.

When you drag a handle and let go, it will snap to the nearest point on the home screen grid.

Some of the electrons pass through the screen grid to the plate, causing a current to flow in the load.

Carrier modulation is applied to the screen grids of both tubes.

It has the three electrodes of a triode and an additional screen grid which significantly changes its behaviour.

Two ensigns were repairing a sensor pad on top of the screen grid.

This connection links the screen grids to taps on the output transformer.

The screen grid of a tetrode neutralizes the space charge and increases the tube's gain.

The control grid and screen grid are also wound with the same pitch, or number of wires per inch.

For example, the screen grid in an EL34 is cooled by two small radiators or "wings" near the top of the tube.

A tetrode can be converted to act as a triode by connecting the screen grid to the anode.

Limits to screen grid dissipation, in addition to plate dissipation, are listed for power devices.

In normal operation the screen grid is connected to a positive voltage, and bypassed to the cathode with a capacitor.

The telephone, a sleek, futuristic model, takes form on a computer screen grid as participants make suggestions and refine the model using a mouse.

Another undesirable consequence of secondary emission is that in extreme cases enough charge can flow to the screen grid to overheat and destroy it.

An important part of the neutralization of a tetrode or pentode is the design of the screen grid circuit.

In this instance the positively charged screen grid can accelerate the electron stream sufficiently to cause secondary emission at the anode (plate).

Psychedelia allowed a user to generate a light show on the screen grid, using the joystick to send pulses or bursts of coloured squares.

In power amplifiers, the majority of this waste heat originates in the anode though screen grids may also require cooling.

The combination of the effects of the screen grid and the damping resistor often allow the use of this design without neutralization.

It resulted simply from the addition of an extra screen grid to the UK version of the pentagrid heptode.

The negative resistance exhibited by tetrodes is due to secondary emission from the anode when operated at a lower voltage than the screen grid.

The output transformers are an ultralinear design, whereby part of the primary winding is fed back to the output tube's screen grid.

In an ECO, The screen grid acts as a plate for the triode oscillator.
