When I built this amp it worked perfectly. However it was my first build and i didn't really solder everything perfectly and there was a lot of wiring that could have been done better. So last week i basically took out the board and re did all the connections. Everything. However now it turns on for a second the light comes on for a second an then my fuse blows every single time. I disconnected the secondaries and took the tubes out and the fuse does not blow. So its not the power transformer correct? Also, I thought i had the power switch, standby and fuse wired differently the first time, but i wasn't sure so I used the robrob diagram and i believe this is what the wiring diagram shows. I've enclosed 2 photos with the secondaries reconnected after i tried that test, as well as a photo of the rest of the inside of the amp. Am I hooking up all the switches and fuse correctly? Am I not putting in the right fuse? would that cause this to happen? Any help would be appreciated. Thanks!
