HF Amplifier, 800W, (4) 811A Tubes, US 120VAC
Only the AMERITRON AL-811H gives you four fully neutralized 811A transmitting 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 sagging and shorting out. Others, using potentially damaging horizontal mounting, require hard-to-find 811A 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 811A 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!
