hello diyaudio,
i am currently looking into methods of building a test load for when i repair and test higher power amps.
im looking for the following criteria :
-4-8 ohms changeable (2 ohm if possible)
-between 1500-2500w of dissipation (fans expected )
-must be able to handle 220v peaks (high rails of pa amps)
-survive short dc input (in case of output module breakdown
theese are the main criteria im looking for, but not limited to, some criteria could be tradedoff.
i found some 500w 16 ohm resistors that might work well for what i need, except the quantity needed to operate 2 ohms would be expensive.
i was also wondering if i could simply use heating elements as load?
would be rather easy to find a 2kw heater and strip the coils.
please let me know what you think or ideas that you might have.
