INTRODUCTION
PWM amplifiers using the SA12 pin-out configuration. It can be
used to analyze a multitude of standard or proprietary circuit
configurations, and is flexible enough to do most standard
amplifier test configurations.
components shown on the schematic will probably not be used
for any single circuit. Some components will simply be omit-
ted, while others require installation of a jumper to complete
the signal path.

tained locally.
BEFORE YOU GET STARTED
* All Apex Precision Power amplifiers should be handled using
* Always use the heatsink included in this kit with TW05
* Always use adequate power supply bypassing.
* Do not change connections while the circuit is powered.
* Initially set all power supplies to the minimum operating
