Zeus MOSFET Matching

L200 current source mosfet matching circuit.

• Use 12 volts for IC1 (STMicroelectronics L200) Vsupply.

• Digital voltmeter to three decimal places at 2 to 6 volts recommended.

• Current set to 500mA (higher current cause device heating).

• Mount DUTs on common heatsink as per picture.

• Allow reading to stabilize (about 10 seconds) before noting value.

• Once close matches have been ascertained retest those matches to get best fits.

The ORIGINAL ROCKFORD FOSGATE PUNCH AMP/ MOSFET POWER

This is for a Older model ROCKFORD FOSGATE PUNCH 75 MOSFET AMPLIFIER. This holds power unlike the newer models. The Punch 75 is 37.5 watts RMS continuous power per channel into four phms with less than 05% total hormonic distortion from 20-20000 HZ.
The side shows Bass 0-18+ and Treble 0-12+.

MOSFET Integrated Amplifier

This is my first attempt at building a "proper" amplifier for general use, as opposed to the Mixer-Amplifier I had made earlier. This amp was made without too much concern to cost, hence several of the approaches I've taken may be sub-optimal from the cost perspective.

Overview

• Microcontroller-controlled preamplifier, with infrared remote control capability. Volume and other settings stored in battery-backed RAM.
• LCD Display for volume, etc.
• Three general-purpose line-level inputs, one tape input, one tape output.
• 70W MOSFET-based stereo power amplifier.
• Headphone output.
• +/-38V at 4A and +/-5V at 500mA power supplies.

High Power, High Fidelity MOSFET Power Amplifier

In various parts of The Audio Pages, I have said that I am not a fan of MOSFET power amplifiers. Well, this amp has changed my views, and I consider this to be a "reference" system in all respects. The performance is extremely good, with vanishingly low distortion levels, plenty of power, very wide full power bandwidth, and the "self protecting" nature of the MOSFETs themselves.

AN10 Automotive Relay Drivers using the Zvn4206av: Protection Free Interfacing with Avalanche Rated MOSFETs: Zetec Semiconductors An alternative solution is provided to the usual large package Darlington effected relay driver. The ZVN4206AV has been designed, processed and rated to withstand significant energy within the breakdown region. This allows the part to absorb back-emf and transient energy, thereby allowing lower component count circuits.

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.
