What makes Ameritron AL-1200 stand out from other legal limit amplifiers? The answer: a 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 is 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 cant 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 cant fail in the AL-1200. Why cant 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 wont 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 wont blow! Will the amplifier you're considering withstand a direct power supply short?

Measures 18 ½" x 17" x 10" .
Weighs 76 pounds.
