I am new to measuring amps. My first effort and the software and test setup are described here:
https://www.audiosciencereview.com/...ement-setup-panasonic-xr57-avr-example.10589/
I have an older Parasound HCA-1000a Power Amplifier that I decided to measure. Specs are here:

Test Overview Photo:
At here are the results, HCA-1000a, 4ohm dummy load, 5watt power, 1khz sine 0dbfs
Comments on my test and measurement setup welcomed. I have a few more pieces of audio equipment I plan to measure in the coming weeks.
