sparda236 23 Posted September 13 Posted September 13 Hi, I’ve been following Sunfire subwoofers ever since I heard a Super Junior at a relative's house—an experience that opened the door for me to the world of DIY audio. As fate would have it, that very Super Junior has now ended up in my hands with a busted cabinet and a blown amplifier (three IRF640s and the 2121/5949 transistors are gone). So, I’ve taken on the task of trying to repair it. Thanks for letting me join the community, and I hope to keep you all updated on the progress. For now, I've been thinking about upgrading the semiconductors—using MJL4302/4281 and IRF640N—but I'm not sure if the 1943/5200 are good replacements for the 2121/5949. Could someone clarify that for me? 6

Looking forward to your project progress. And, it goes without saying..., we LOVE pictures! Just cut and paste into the editor with Windows Snippit, or Apple's similar. On your project..., I suggest rebuilding it to OEM, before changing anything out as a mod..., it will simplify things, and you'll know you got it working before the mod - vs., doing both at the same time, and not knowing what part of the changes caused the failure. Again, welcome to TCS! 1
BobTFM35 3,361 Posted September 15 Posted September 15 @sparda236 If I may offer a suggestion to possibly get better exposure for your question. I would create/start a new topic/post in this area, https://thecarversite.com/forum/137-sunfire-speakers/ @Sk1Bum 5
Sk1Bum 13,666 Posted September 15 Posted September 15 @sparda236, I agree with @BobTFM35. If you will start a new thread in the area that BobTFM35 linked to, I'll be happy to move your post to the new thread. No worries, no harm, no foul. Easy-peasy. 2 1
