OK I finished up my Super 5f4 build today and I was having problems with the bias circuit I had to build for it I figured that out and had -40 to -50 V DC so finished wireing up the last couple wires I needed to finish which was the wire from the Recifier pin 8 to the standby switch and the wire from the circuit I made for the bias voltage to where it goes on the board. Now the board I bought pre- loaded and the guy leaves the ground wires bare. I did not need to dress them in my last build had plenty of room so I did not on this one either which was a mistake as the ground wire for the filter cap which is the left one of the three 16 MFD caps blew out the side of the cap after I fired up the amp. After looking I saw that the ground wire for that cap connection had moved against my input jacks and was touching the positive prong of the input jack which shorted out the cap. So tomorrow I will go get a cap from my tech friend and wire it in and hopefully all will be ok. So do you guys think the cap took the brunt of the damage? every thing else looks ok. Oh and I dressed the rest of the wires to make sure nothing shorts out again.
