I need help to get this EV GRAY type system to work

Yes, it sure looks like you do live in Aladdin's Cave of electronic treasures :-) .

Why not do us all a fav and post the #'s of that tube. That is a whopper. Curious as to what its intended use was. Used to have a few old transmitter tubes for FM but all got lost in the move.

i am still waiting for directional help and support. thank you all

Thank you very much for sharing.
If your system power is about 3kW, I think the 1N4007 may have too little current.
It may be better to use 30A600V diodes to connect three in parallel.

It is necessary to determine the cause of the damage to the diode.

If the diode withstand voltage is not enough, resulting in reverse voltage breakdown,
The diode is added in series.
If the diode current is not enough, resulting in overheating breakdown,
Diodes are added using the parallel connection method.

If the circuit runs for a while, it feels hot and then it is damaged.
It may be that the diode current specification is not enough.

If the circuit starts running, the diode is immediately damaged.
It may be that the diode withstand voltage specification is not enough.

Good luck with your experiment.

  This has been bugging me now since I posted last. If you are using the 1n4007 they are 1000v at 1A. The non polar cap is what is bothering me. If that causes a reverse voltage to happen then it is good to 700v. But...... only5 mico amps so would not take much current to toast it.
  Just thinking out there cause it may cause osc to happen. Would depend on how long your wires are to the diode and cap. If this is out of it, plz correct me as it will clear up a possibility for me.

That original circuit, witch rubish bin did you get it out of ?
it wont do longdetutinal waves or standing waves and 1n4007
diodes wont work as they have only a low frequency and a
1000volt capability blocking capability inc forward voltage.
