No fault of my own incompetence of amp building here. I have a huge amp. And it’s ******* New Year’s Eve!!!! It’s time for 7 year old disco party. I uncorked the amp (flat amp x3??? =louder) and bang, 1700 (time of day) dead big amp.
quick headlamp amp swamp to stand by class D (?) Akitika GT-102 and we’re back to New Years karaoke.
ya know how James Webb Space Telescope has a few “single point failures” well, my Pass F5T has about 16 single point failures, and one of them cooked. Heh heh
more stories from the trenches!!!
happy new year.

I think I found out what happened. One of the speaker wires had come off the terminal and made contact with the case. <face palm> Now it's time to pull that open and find the smoke... order parts, wait a month. blah! Lesson to me to properly terminate wires instead of just slap 'em on there.
Damn not so fun .... have burned my share of amps myself 😉
Maybe a heretic, but I use Neutric Speakon on all my amps ..... better, cheaper, safer 🙂

I was so happy to find it was just a fuse. So I replaced it… hmmm another fuse. I’d ran out of identical fuses, so I put in a … larger one. Now there’s some action! Smoke and fire from one of the IRFP9240. There’s something I can fix. Remind me to get the video rolling before hitting ON switch next time.
What’s the best way to proceed? I’ll certainly need at least a new MOSFET.

Do you think you're getting enough air around the chassis, especially the top? Is the top panel vented?
Yes, the chassis is vented top and bottom. The top and bottom were off at the time of the fire.
Why don't these have SOA/SOAR protection to stop the amplifier blowing up in the event of an accidental short?
