Smoking crack after speedball

Can you check the voltages on the front board with just the 12AU7 plugged in?
Can you pop the 4 wires off the big PC board and post a pic of the bottom?
Can you try the 6080 we provided now?
tried my 12au7 and cv4003. Is this safe to use then?
I think you may just have an issue with the other 6080 you have.
We have no idea what's smoking and why. Generally you would check the voltages to see what's incorrect. If this was happening but isn't now, it could be debris in the amplifier that was causing a short but has been dislodged, or some other bits touching that shouldn't be, which have now been moved apart.
I have never seen a defective 6080 do what you're describing, so I believe it would be a mistake to assume this is tube related.

You can get a bad 6080 that will draw down the power supply and make the 270 ohm resistors in the power supply discolor, crack, then blow. The writing on yours still looks perfect though, I don't believe that failure mode is at work here.
