old fashioned 535 - first start after 35 years


Michael Petereit
 

Hi,

now I finished the repair of this pretty old scope. I switched on and
was afraid of getting "flames" out of it.
This didn't happen but even after 10 minutes running no beam appeared on
the tube.
Since the servicemanual describe resistors and capacitors with it's
number within the system the reality looks different.

I cannot measure neither 9kv voltage nor I can find the correct part
cause the scope is pretty dirty inside.

Any hints where to look first ?


Thanks,
Michael
