RM Italy MLA-400V HF Amplifiers cover all Amateur Bands, 160 through 10 meters providing up to 400 watts output on HF with only 35 watts maximum input. These amplifiers are the perfect choice for operators that want to bump their 100-watt radio to a higher power level. Featuring four Toshiba 2SC2879 arranged in a parallel push-pull configuration, the MLA-400 provides clean Class AB power output up to 400 watts. Six Low Pass filters with frequencies of 3, 4, 5, 8, 15, 22, and 31 MHz reduce unwanted harmonic output and may be selected automatically or manually. An onboard microprocessor controls all aspects of the amplifier including its various protection circuits. Protection is provided for excessive input power, excessive output power, excessive load SWR, out of band operation and excessive temperature. The four Toshiba 2SC2879 MOSFETs are attached to a chassis sized heatsink that has two fans for additional cooling. The front panel features indicators for the currently selected band, power output SWR, protection alarm, transmit indicator and SSB delay. The rear panel features SO-239s for input and output, a female RCA for a PTT line and the power connector. The MLA-400V requires 70 amps at 13.8 volts DC and can be used either in a fixed location or in a mobile install. The chassis has points that can be used for securing the amplifier in a mobile installation.
