Ameritron Al-811 linear amplifier gives you plenty power to bust thru QRM. You get a quiet desktop linear thats so compact itll slide right into your station -- youll hardly know its there ... until QRM sets in. Conveniently plug it into your nearest 120 VAC outlet -- no special wiring needed. Three tough 811A transmitting tubes, extra heavy duty power supply, all HF band coverage, pressurized ventilation, tuned input, dual illuminated meters, adjustable ALC & more. The first 600 watts make the difference The Al-811 gives you 600 watts PEP output -- thats nearly 2 full S-units over your barefoot rig.

How the low cost 811A tube resists premature failure -- even when your amplifier is mistuned First theyre constructed with widely spaced elements that minimize the chance of touching and causing a short -- even if the plate gets hot enough to melt. Second they use a directly heated thoriated tungsten filament cathode that prevents the electron emitting layer from instantly stripping off -- even if mistuning causes a sudden, sever current overload. The Ameritron AL-811 is excellent for the newcomer because its tough enough to withstand momentary mistuning. And the tubes are so inexpensive t
