I have acquired a d75 o'scope. have no manual. unit shows normal trace for several minutes then trace disappears. I think the power supply quits. Does someone have p.s. diagram or voltage readings for some pins? Scope has not been used for a long time. (years?) Thanks, Tom

 

Hello,

There is nothing wrong with the link Bertus supplied. It is a link to the Boat Anchor website. A website for manuals of old test equipment.

 

The manuals for the site have been down. There is a mirror out there, I also found it, but do not remember where. A search engine should find it.
