[Amps] Big HV Supply

[Herbert Schoenbohm]

I have a large brute 70 lb HV supply that came from an amateur QRO
amplifier where what is inside is two big relays and no rectifiers.  There
are two cables.  One for AC power and the other that takes the HV AC to the
amp where the rectifier and capacitor stack existed. I wonder if there is
anyone in the group that can identify the name of the company that marketed
this amp and supply combo?

Please let me know.
