What is the best proceedure for testing Audio ouput transformers, every second thing you seem to read mentions different ways.
When testing Audio output transformers is it best to sweep through the frequency range or test at frequency increments working up to the maximum frequency.
Also, some say to test with a sinewave & others say test with a squarewave.
Some seem to test with very low amplitude input signals compared to the actual working enviroment.
It all becomes some what confusing when you read so many different techniques.
I would have thought that at a minimum you would have to test with at least the same amplitude & frequencies as the output transformer will be subject to & transient test by sweeping though the frequency range with a similar signal to what the transformer will see, not static testing.
Maybe I am completely wrong also?
Could someone help me with an explanation of the correct way to look into this & what to look for regarding what you do NOT want to see when testing.
Cheers
