Are you using one of the BG7TBL noise source?

.
I think yes, because after triggers purchased it and posted about it in 2015, I also purchased same/similar model.

New model of BG7TBL noise source

I purchased the one in picture below last year. It failed after one week. It generated so much heat that during it’s one week life, I used it for frying eggs. https://farm8.staticflickr.com/7077/26858907955_d2119c4ed6_o.jpg
