Nice

Agreed, the bad ones could indeed do such.


A few rhetorical questions (till I can get a copy of the paper..)

1. I make the assumption that they measured a fully loaded amplifier. What load did they use?

2. Was their load capable of pulling current at (inverted) nanosecond speeds, or was the amp coasting at the hf?

3. If a reactive load is substituted, are the measurements the same?

4. If the test signal amplitude is changed, do the results change?

5. If the amp is pushed to output limits that mess damping factor up, does that alter the results?

6. What about measurement of the 6K signal, not the carrier. we're not very sensitive to ITD at 60 Hz..essentially, will the "carrier" time modulate the hf?

It sounds like the paper is basically tending a go-no go type of test, but again, I'll have to read it to see if what they did is consistent with what I speak of..

Thank you, you're a wealth of info..

Cheers, John
