Icepower 500a

Hello there.

Are someone here using icepower 500a? I have 1 unit and its break, blown up something like thst. The main issue is the thick resistor LTO 30 5ohms the t220 package resistor. The problem is the thick resistor blown. I replace wirewound resistor 50w 5omhs. And Its working great sound i think its back to normal ( i wish 🙂 ) but after 20 to 30mins the thick resistor is too hot you can cook egg on the top of it 🙂 i try to search in electronics store here in PH , but sadly no available 🙁 ..... is there anyone here replace or bypass this resistor? Thank you

I have a 500ASP and the equivalent part (attached to the heatsink) does not get hot. Do you also have the replacement 50W resistor attached to the heatsink? Does the 50W resistor get hot with the amp at idle (no signal)? Does it get hot with a pure resistive (speaker) load?
