Re: Infinity TSS-450 sub assistance
So I replaced 11 of the 12 small caps.... I missed one when ordering. I also re soldered a number of the transistors.
Result is the same. about 5 min then humming popping and general terror starts.
Any other thoughts?

Re: Infinity TSS-450 sub assistance
Thanks for the time looking at this. I will pull and log all the caps specs and their board locations. I have been successful purchasing from digikey before so I will try them first.
After I get all the caps replaced and the tan glue cleaned off I will let you know how it all worked out.
Thanks again for the space and the assistance!

Re: Infinity TSS-450 sub assistance
Here you go, you can see the discoloration on the board where it got hot.
Thanks for any help you can provide.

Will do the next time I am at home. I have the board pulled out already. Thanks!

Re: Infinity TSS-450 sub assistance
Is there a method of testing these transistors? I am assuming the mosfets are attached to the heatsink.

Infinity TSS-450 sub assistance
Hello,
I have this TSS-450 sub that has been great for 7 years, It recently started making noise after about 3 min of running (works flawless at first). It starts with a hum and then all hell breaks loose when the squelching vibration starts in.
I pulled it apart to find some pretty warm areas under a few 3 leg transistors? And a couple of the small caps.
Any direction on where to go now would be great!
Thanks
Josh

Re: New Members - please post your introductions here
I stumbled across this site, and was really pumped to finally find a place that actually has helpful information and members.
I tune engine management for Subarus and fix as much as I can regularly.
Thanks
Josh
