Hi Michael,
The black capacitors I am talking about are located in the -150, +100, +225,
+350, and +500 power supplies and not in the high voltage area. You should
be able to remove and replace these capacitors without removing any other
parts. If one of the precision resistors in the power supply gets damaged,
I have some spares from scrapped old scopes.

Hi Stan,
the plugin is available and installed. Unfortunately one channel will
not work for sure since the wire of one coil is broken....
But this won't prevent the startup of the complete "vehicle".
For checking the black old capacitors I have to unsold all other
resistors above. For cleaning purpose this is the best choice but a
little bit risky too.
Thanks,
Michael

Hi Michael,
Something I forgot to mention that you may not know is that for the power
supplies in a 535 to work, it MUST have a plugin installed, otherwise, the
load on the power supplies will be too light and they will not regulate.
