Problem with my G5 amp

[Papa_Mateo]

Good Evening, i used another layout from tube town store. Now Stand by switch is good connected. I spoke with one Man and he said that could be problem in 12ax7 tube. El34 was broken down, but IT might be that i killed preamp tube also. Tomorrow i will try once more with new 12ax7.
Best regards
