Thanks for the replies all,
The guy that gave them to me was a medical equipment repair tech years ago...
When stuff actually got repaired,remember those days?
I got rid of 98% of my stuff,just kept a Tek 504,and an Owon 2 channel LCD
unit.
I wanted to get a 2 channel CRT scope for a " Scope Clock " kit I built,it is not as impressive on the LCD screen :-(
Naturally I was hoping for a quick fix as I do not have to much patience for a value-less solid state unit...
I'm going to have to open one of these up regardless... The dirty circuit board pins seems like the best answer sofar.As these scopes have been sitting for a long time in a garage,and the flickering power light is erratic like something breaking down under a load.
If/when I open one up I will post if anyone is interested....I will post even if
no one is interested
