Hello, Is it possible to use dummy load ( 4-8 ohm, 300W high power resistor ) in replace of original speaker attached to the TPA3255 amplifier ?? Can this load destroy the chip, because it is not active load or it is OK for TPA3255 ? Thank you in advance, Emil6...
Step 10: Testing an Amplifier To use the dummy load, simply treat it as a pair of headphones and attach it to a phone/MP3 player/headphone amplifier. Then scope one or both of the channels while playing something - standard practice for testing is to use apure 1kHz sinewaveand measure t...

After years of using high wattage power resistors, I'm considering upgrading to get a DC electronic load for using as a dummy load to test power supplies. Most of the time I'm dealing with smaller PSU's based on LM317/337 and 78XX/79XX, but occasionally deal with some bigger console...
