Yes, this cartratige works, but if you can, shell out for a better one. There was significant background hum at higher volumes and the clarity of sound produced is only average. Buy it if you're on hard times, but keep shopping if you're not. Reasonable to install, did not encounter product defects, it's just too low-end for an audio enthusiast.
