Review: The Ameritron ALS-600 600-Watt HF Power Amplifier

Phil Salas – AD5X

Introduction

While more and more new solid-state HF power amplifiers continue to show up in the

ham market, one solid state amplifier that has been around for quite awhile is the

Ameritron ALS-600. This is an HF-only (160-10 meter) amplifier with manual band

switching, 600-watts output power, and no microprocessors. However, these reduced

specs result in a modestly priced solid-state amplifier that can operate from the standard

120VAC wall outlet. And 600-watts is significant , giving you a gain of almost 8dB

which is over an S-unit more than your typical 100-watt transceiver. This is normally

plenty to make the difference when chasing that DX. And remember, 600 watts is only

4dB down from full legal limit .

The ALS-600 Amplifier

The ALS-600 consists of two separate units – the amplifier itself, and a separate

50VDC/25 amp linear or switching power supply. The amplifier and power supply can

be separated by up to 6-feet with the supplied power cable, letting you place the amplifier

at your operating position and the power supply out of the way. Both units are very

compact making this amplifier/power supply combo convenient for portable and DX

operations. Photos A and B are close-up photos of the front and inside of the amplifier.

The ALS-600 uses four Motorola MRF-150 TMOS FETs operating at 50 volts to provide

the 600 watts typical output power. In order to protect the amplifier from user mistakes

or antenna system problems, reflected power in excess of 75 watts causes the amplifier to

be automatically bypassed. The amplifier heat sink temperature is also monitored, and

the amplifier is bypassed if th is temperature exceeds a safe value. Whenever the

amplifier is bypassed, you can restore it to normal operation by first clearing the fault and

then simply switching from “Operate” to “Standby” and then back to “Operate”.

The ALC interface is unique in that a rear ALC adjustment is user-adjusted to customize

the ALC range for virtually any transceiver. Once this control is set, you can adjust your
