Help Needed with ADSR Problem Solving

[valis]

Well this hasn't been a particularly good week for keeping my modules running. Anyway, I had a working ADSR that I think I short-circuited trying to test a few things out. Now all it puts out is a steady voltage that is determined by the output Level pot (0-13v). Such voltage does not change when triggered.

I did some voltage tests and everything works fine and all the chips are receiving their appropriate power. That being said, there's something fishy going on with U5 (TL084). The chip is getting the appropriate voltage but it is getting extremely hot.

I swapped another TL084 in but with no success.

Sorry I keep going to the well of knowledge that is EM with my problems. Any help is appreciated.

Like I said, it was working and now it's not. I'd love to learn why..

Thanks for your reply. I searched the board for shorts and faulty wires but didn't find anything. I suspected the tantulums and electrolytics but no luck there..

The winner was a faulty 4066 chip. I replaced it and all is well. Phew!

Thanks!
