AMERITRON AL-811H HF AMP 4 811A TUBES 850W PEP ***PLUS FREIGHT** $35 flat freight to Lower 48
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!
