Amplifier Work

What is this.......
It's two 7,5 kV 500pF door knob capacitors.
Sitting inside my amplifier.
In front of a 3cx1500 tube from Eimac.
I realy hope this will bring my Ameritron amplifier back to life.
This amplifier has been a very good work horse for me.
The old capacitors was going with a big bang att 0500 o'clock
in the morning, wakeing up the whole house....
And i get a good Picture about what my wife was
thinking about my radio hobby.......
A big thanks to LA8LGA Jens who was giving me the parts...
