A 300w MOSFET Linear Amplifier for 50 Mhz

A 300w MOSFET Linear Amplifier for 50 Mhz: Advanved Power Technology - APT980

25 Watt MOSFET Amplifier

25 Watt MOSFET Amplifier: High Quality simple unit. No need for a Preamplifier

2N2222 40 Meter CW/DSB Tranceiver


power Redefined

The Hx350 is the epitome of power.

With 10 pieces of IRFP240/9240, it is capable of delivering an astounding 600Watts/RMS into 4 W (before clip).

But the Hx350 is more than raw power. It's about the quality of Watts. It has none of the edginess and harshness that proamps are notorious for. When used in the home, the Hx350 is ideally suited for high powered subwoofers or power hungry main speakers.

The Hx350 is the only amplifier in AmpsLab with our Loudspeaker Protection Circuitry (DCpro Kit) on board.

Lateral Mosfets

The Lm60 uses a pair of highly acclaimed Hitachi Lateral Mosfets 2SK1058 & 2SJ162 for the current stage.

These mosfets are reputed to be the only transistors manufactured solely for audio applications. Unlike normal power transistors, the Hitachi Mosfets do not suffer from Secondary Breakdown. Best of all, they are immune to Thermal Runaway.

In musical reproduction, the Lm60 is probably the sweetest sounding amplifier in AmpsLab. Highly recommended for tube aficionados who are migrating to solid state.

Switching Mosfets

The new generation of Switching Mosfets, IRFP240/9240, are making sweeping changes in power amplification.

Since these mosfets do not suffer from Secondary Breakdown, they are fast gaining reputation as the preferred choice in the professional industry.

The Hx series in AmpsLab takes full advantage of this new technology. We highly recommend our Hx amplifiers for Home Theater Systems.
