What the heck did I do?
« on: July 07, 2015, 07:10:23 pm »
Had an AC 30 on my breadboard. Connection to one lead of my primary OT came off. Not the CT. Heard a pop and my (mains) fuse blew.


Connected OT. Put in a new fuse. Powered on, and as soon as I flipped standby I saw smoke roll off my 1.5k grid resistors on one of the pairs of EL84's. Now I dont know if it came off the the pair that was previously disconnected from the OT or if it was the pair that was not disconnected.

I quickly turned it off. I hope its not the OT. Somehow im getting a crazy current flow. I havent even looked into the amp yet. I wanted to ask here first.
