Drive the amp with a variable frequency sine wave generator and get the biggest audio power amp you can obtain, say about 100 watts. be sure the transformer can take the power, and monitor both the input and output of the transformer with two channels of an oscilloscope to be certain you are dealing with undistorted sine waves throughout. | |
