I show you how I test an amp I just got used, So you can do it yourself with some basic tools.
Oscilloscope Testing of the Audio Amplifier.
http://www.r-type.org/articles/art-125.htm
AF amplifiers can be tested with an oscilloscope by making sequential stage checks, using a sine wave input. The circuit of a typical 10 Watt high quality valve amplifier is given above, and the circled numbers in this diagram indicate the test points to which the oscilloscope may be applied, and the order in which the checks should be made.

there are several parameters you can measure. Frequency response, distortion, SNR, just to name a few. I mostly used Audio Precision equipment for measuring/testing audio parameters, maybe you have the chance to get access to one. For a "rough" measurement I would recommend to use your sound card and REW [1] to test.

June 20, 2014. George. An oscilloscope can display the shape of an input signal wave, enabling you to observe waves and test electrical currents. You can use an oscilloscope to test your audio amplifier for blown fuses, improper biasing, signal distortion, and other sources of poor sound fidelity. Older style oscilloscopes display the wave on a cathode ray screen …
