as PA has indicated,

Sorts out the "serious" ones.



Yep, those are the exact same resistors as I am using, but in the 100 watt
flavour. Heatsink the size of the Titanic with a matching fan bolted to
the end, but mine runs all the time. Has proved very useful for repair of
high power PA amps, where the owner complains of things like " cuts out
half way through the second set ". I can now leave the amp thrashing away
into this load, with the scope hung on the socket I've provided.


** If all you want is to heat up a power amp and see when it shuts down -
no heat generating dummy load is needed.

An air cored, 5 mH inductor load driven at 200 Hz does the job FAST !.

Impedance = 6.3 ohms.

Phase angle = 90 degrees.
