800WATTSOUT...$799!

Only the AMERITRON

AL-811H gives you four

fully neutralized 811A trans-

mitting tubes. You get

absolute stability and superb

performance on higher bands

that can’t be matched by un-

neutralized tubes.

AMERITRON mounts

the 811A tubes vertically --

not horizontally -- to prevent

hot tube elements from sag-

ging and shorting out.

Others, using potentially damaging hori-

zontal mounting, require hard-to-find 811A

tubes to retard harmful sagging and short-

ing.

Powerful 20 CFM computer grade fan --

not an open frame phonograph motor --

draws in cool air to pressurize the cabinet

and efficiently cool your 811A tubes for an

extra long life.

Yo u also get efficient full-size heavy

duty tank coils, computer grade capacitors,

heavy duty high silicon core power trans-

former, slug tuned input coils,

operate/standby switch, transmit LED,

ALC, dual meters, QSK compatibility with

QSK-5 option and much more!

AMERITRON Amplifier-to-Transceiver Interface Protects expensive radio from damage by keying line transients and steady state current and voltages Amplifiers can damage radios if the amplifier has too much relay control voltage, voltage spikes, or excessive current on the relay control line. Such damage often appears as “stuck” or “sticky” transmit relays in exciters or shorted transistors on transmit control lines.
