Hi NWM
I have been looking at the Saalburg 5170 on the Radio Museum.
From the photos on there it looks like once unscrewed, and a few wires to the speaker transformer etc removed, the whole chassis will slide out backwards together with the dial, knobs and push buttons.
The printed circuit looks like it is accessible from under the chassis and the components from above the printed circuit. It should be even possible to spray switch cleaner into the push button switch cases. R12 could be checked for continuity, and maybe the fault identified.
I appreciate that you like to learn for yourself but I feel you may be making the job more difficult than necessary, this may add more faults than were originally there.
Of course I am not the one sitting in front of the radio, so cannot see precisely what you can see, there may be some reason the chassis cannot be removed from the radio and worked on, so please tell me to shut up if I am talking rubbish.

If the push button switch assembly really has to be removed then It may be possible to do this once the chassis is removed from cabinet and the knobs and dial glass have been removed, there may be no need to remove the push button caps.
