Manufacturer's logo / date code / other markings - ?

Thanks for your reply The damaged part has lost the identifying marks Its purpose was to store energy, almost square waveform "Edmark Type" I can´t find in the service manual any description of its manufacturer or.model only this in the schematics: I am attaching the service manual and a section of the schematics showing the capacitor

All caps & BOLD means you’re yelling…
Disrespectful when you are addressing the @AnalogKid.
An analogy would be when playing poker, (five cards stud) and you’re holding aces and eights. Which is, of course…“the dead man’s hand.”

In function bar across the top of the edit window, the TT dropdown lets you adjust the font size. On another forum I scale all of my posts up to 15.
