AMERITRON’s AL-1500 will give it to you. Using the Herculean 3CX1500A\/8877 ceramic tube with its high power gain, the AL-1500 needs only 65 watts of drive from your exciter to deliver the goods-- transceivers and other exciters just loaf at 1500 watts out.\u003c\/p\u003e\n\u003cp\u003eCool, efficient operation is provided by a forced-air system with tube chimney, using a commercial grade die-cast ball bearing blower for maximum tube life. The tube is further protected by time delay starting and automatic over-current shutoff to remove drive power if the amplifier is mis-tuned.\u003c\/p\u003e\n\u003cp\u003eYou get full legal power output from a whisper quiet desktop linear. Measures 18 ½\" x 17\" x 10\" inches, and covers all bands, 160-15 Meters, including WARC and MARS (80% of full output set to nearest amateur band). 10\/12 Meters modifiable.\u003c\/p\u003e\n\u003cp\u003eYou get 1500 watts output (1\/2 hour continuous carrier) and 2500 watts (30 second continuous carrier and 2500 watts- plus 30 minute PEP two-tone test). You get all this power, plus, 65% efficiency, pi-net-work tuned input, Pi\/Pi-Loutput, inrush current protection, multi-voltage transformer, QSK compatability, and a one-year warranty.\u003c\/p\u003e\n\u003cp\u003eThe guts of the AL-1500 is its heavy duty power supply, with a 32 lb. Hypersil® transformer using a high silicone steel core, computer grade capacitors (33 mfd total), heavy duty bleeders and twenty 3 amp, 1000 volt power rectifiers give you a stiff 3300 volts fully loaded.\u003c\/p\u003e\n\u003cp\u003eThe AL-1500 is built on a rugged steel chassis with a separate RF compartment fully shielded to keep RF from leaking out, keeping RFI and TVI to a minimum.\u003c\/p\u003e\n\u003cp\u003eSuperb RF design and layout, Hi-Q tank circuit and commercially rated RF power components give you 65% plate efficiency over the entire operating range. Power goes into the antenna instead of into heat.\u003c\/p\u003e\n\u003cp\u003e50-ohm broadband Pi-Network tuned input with slug-tuned coils is used. Even fussy solid state transmitters deliver full power!\u003c\/p\u003e\n\u003cp\u003eA carefully designed Pi\/Pi-Loutput network using the optimum Q for each band with vernier ball drives gives smooth tuning, wide matching range, full band coverage, and peak performance at all power levels.\u003c\/p\u003e\n\u003cp\u003eThe AL-1500’s grid overload circuit protects the tube from excessive grid current; if 175 mA of peak gric current is reached, the “OPR” LED will no longer light and the amplifier will go into a bypass condition until reset by the operator.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003ci\u003eTransformer provides many options\u003c\/i\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eSince excessive line voltage stresses components (low line voltage causes a “soft tube” effect, for example), Ameritron’s exclusive Multi-Voltage Power Transformer™ lets you optimize for different line voltages. Select from 4 different primary voltage ranges, from 205-219 VAC to 252 to 265 VAC. The amplifier comes wired from the factory for 240 VAC.\u003c\/p\u003e\n\u003cp\u003eThe AL-1500 has two illuminated panel meters. Grid Current meter provides continuous reading of the critical grid current and indicates proper, safe amplifier operation.\u003c\/p\u003e\n\u003cp\u003eThe other meter can be selected to read Plate Voltage, Plate Current, Peak RF Watts, or ALC. A SSB\/CW selector switch chooses bias voltage for best linearity on SSB or lowest dissipation on CW.\u003c\/p\u003e\n\u003cp\u003eThe Operate\/Standby switch, in Standby, maintains the tube’s filament and plate voltages while allowing “barefoot” operation.\u003c\/p\u003e\n\u003cp\u003eIncludes 12 volt DC auxiliary jack and an “XMT” LED to provide indication of proper amplifier keying by the exciter.
