Some components on the chassis looked like they were missing, and some resistors were badly burnt making it difficult to identify them. But spectroman here on the forums was kind enough to provide me with some schematics for the chassis so I have now been able to replace those. Also, I recapped one of the chassis-pcbs (there are two) and now she fires up! At least one of the pulled caps was shorted.
The picture still needs adjustment, but I will wait with that until I have recapped the other board. So, thanks a lot spectroman!
