AL-811HD 800 Watt Amplifier

AL-811HD 800 Watt Amplifier

Get the AL-811HD with 572B tubes
AL-811HD gives you the AL-811H with four 572B tubes installed. Get a higher power tank circuit and grid overload protection. Grid Overload Protection protects the tubes from excessive grid current due to mistuning and it protects against excessive drive power. Four 572B tubes give you more plate dissipation than a single 3-500Z tube. AL-811HD gives you 800 Watts output in SSB and 600 Watts for continuous duty in CW, RTTY, SSTVand AM operation.

AMERITRON mounts the 572B tubes vertically, not horizontally, to prevent hot tube elements from sagging and shorting out. Others, using potentially damaging horizontal mounting, require hard-to-find 572B tubes to retard harmful sagging and shorting.

Powerful 20 CFM computer grade fan, not an open frame phonograph motor, draws in cool air to pressurize the cabinet and efficiently cool your tubes for an extra long life.

You also get efficient full-size heavy duty tank coils, computer grade capacitors, heavy duty high silicon core power transformer, slug tuned input coils, operate/standby switch, transmit LED, ALC, dual meters, QSK compatibility with QSK-5 option and much more!

SPECIFICATIONS:
• Output power: 800 Watts PEP, 600 Watts CW.
• All Band Operation: Covers 160-15 Meters including WARC bands. Can be user modified for12 and 10 Meters.
• Vertical Tube Mounting: Prevents shorting of tube filament/grid, prolongs tube life.
