Hey Guys,
Just after a bit of help re dummy loads for testing comps/power amps etc
What sort of power handling do the resistors need to have? Presumably greater than the power output of the device under test yeah?
So I thought of making a switchable dummy load with some 4 ohm 50W resistors on a heatsink, in a box to test some guitar amps... I had read about suspending them in clean oil for heat absorption but am not sure about this.
What about a 600ohm for testing La2a/STA etc?
Also, can anyone recommend some good books for learning about general audio circuit testing/troubleshooting?
Thanks for your time (and patience with the N00b)
Kind Regards,
Matt
