Someone with a HAMEG 303-6

[PartialDischarge]

Just got a  HM303-6 and the seller told me it had a problem in one channel but forgot that the timebase was also screwed. With the service manual of the 303-5
I was able to repair the channel (a JFET gone bad), but the timebase seems to have 2 missing components, one of them is a cap, whose value I've been test-guessing,
but there seemed to be other not shown in the 303-5 schematics.

So anyone with a 303-6 is willing to open it quick to look what these 2 components are and maybe their values???

The timebase board is readily visible after the cover is removed.

Thanks
