I've got one bad triac on a controller from last year - haven't gotten around to replacing it yet but will note the details.

I had one go bad last year, but I haven't seen anything this year. I will keep an eye on it.

I have a bad one that I'm replacing this weekend. I'll let you know. It was most likely from that group buy.

I am noticing some inconsistencies with my snowfight wireframe this year (3rd season). Out of curiosity:

1) When the triacs are going bad, are they 100% bad, or will they sometimes work and sometimes not work? One segment is starting bright, then going dim a 1/2 second later, that is most defintely a triac issue in my mind, but the ones that work sometimes and not others seem a little bit more odd to me.

2)When was this group buy? I did participate in one, but it was a couple of years ago, it wasn't real recent.

I about about 75% sure that this one is my fault though. (I think this was the channel that had the 150watt floods on it - and that had the flood holder melt.)

I have one other controller with channels 12 and 24 out - but - not 100% sure thats the controller.
