John, what kind of load resistors do you use in testing? Obviously, they can take way more than 1kW per channel.

John, what kind of load resistors do you use in testing?
For testing high-power amps I use an array of four non-inductively wound 8 ohm resistors, each with its own heatsink, mounted on an aluminum plate. They are connected in series-parallel to give a combined load of 8 ohms.
Obviously, they can take way more than 1kW per channel.
Only in the short term.

Hi JA
In figure 8 there is an enharmonic peak at 180 hertz
Do you know what this is....power supply multiple ?
