Stijn A very nice picture of the complete system. I assume your in the Netherlands. I actually have seen various components in a basement in NJ. At least I am pretty sure thats what I had seen. But that also means shipping would be very costly.
With respect to the oscillator I agree with Bob return it to the original state if possible. These days finding the types of parts that are used in the system are becoming more difficult. 1/2 watt and larger resistors that can handle the various voltages. At least with tubes while hamfests still existed they actually didn't seem that hard to come by. I picked up numbers of NOS tubes for WWII radios without any issue. They worked well. Would be great to see the system working again. Then you can hook up a GPS system to it and make the worlds most heavy GPSDO. Good luck.
