What makes Ameritron AL-1200 stand out from other legal limit amplifiers? The
answer: a super heavy duty power supply that loafs at full legal power - it can deliver power of more than 2500 watts PEP two tone output for a half hour!

The heart of the AL-1200 power supply is a highly efficient Peter Dahl tape wound Hypersil transformer weighing 32 pounds. -- it's equivalent to a 45 pound transformer using standard E-I laminations.

High Current computer grade capacitors
You get genuine high current, full height computer grade capacitors with screw-on terminals -- not short stubby, light duty soldered in "capacitors" that can't dissipate the heat generated by high current.

Why some filter capacitors explode
The failure of carbon equalizing resistors -- used in most amplifiers -- is the primary cause of filter capacitor failures. When a carbon resistor gets hot its resistance drops, causing more current to flow, causing the resistor to get
hotter. This destructive cycle repeats until the carbon resistor opens and causes excessive voltage on the capacitor -- the capacitor can explode. Carbon equalizing resistors can't fail in the AL-1200. Why can't they fail? Because no
compromise wire wound SEVEN WATT 50 K ohm equalizing resistors -- not the 2 watt 100K resistors others use -- safely protect each filter capacitor. Plus, the lower value gives you better voltage regulation.

A Direct short won't blow these rectifiers
The AL-1200 rectifier board uses diodes rated for a massive surge current of 200 amps -- you can accidentally short the high voltage supply and the diodes won't blow! Will the amplifier you're considering withstand a direct power supply
short?

Eimac 3CX1200A7: The durability of glass and the power of ceramic
The AL-1200 uses one of Eimac's toughest ceramic transmitting tube -- the reliable 3CX1200A7. It has the durability of glass tubes and the power dissipation of ceramic tubes.

The Best of Both Worlds
A 3CX1200A7 has the lowest history of field replacement of any modern transmitting tube that we use. It has the ruggedness and power handling of ceramic tubes combined with the long life of thoriated tungsten filaments. The UPS shippable AL
-1200 also gives you ... all mode, all band coverage including WARC and MARS, Pi-network tuned input, Step-Start Inrush Protection, multi-voltage primary, Pi-L output tank with silver plated components, separate filament transformer
eliminates poor regulation and surges, adjustable ALC, SSB/CW switch for best linearity and efficiency, operate/standby switch, transmit indicator LED, 12 VDC auxiliary output, 35% safety factor for tuning capacitors and bandswitching
virtually eliminates failures, shielded RF compartment, quiet die cast blower has 4 speeds, two illuminated meters show continuous grid current, peak RF watts out, drive power/ALC, plate voltage and plate current, ball bearing vernier
reduction drives on plate and load controls, optional QSK board, one year limited warranty and more.
