Just finished building the crack. I checked the resistance before plugging the amp in and all readings matched the manual's. I inserted the tubes and plugged in the amp.
The 12u7 tube glows, but the 6080 tube doesn't. The LED's glowed for a short while, but stopped after 2 minutes.
I measured the voltage on the 9 socket and got voltage higher than listed. There was no voltage for the 8 socket. Now when I measure either tube socket, I don't get any voltage at all.
The fuse is still fine, and the 8 tube socket is in the correct orientation. Is there any way to fix this?
