| 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.
