Well I ended up purchasing one of the new stereo FM decoders as I've read good things about them. Now I can rebuild the set without worrying about the decoder not working and will rebuild the original later. The decoders were optional in the Saba sets during the early stereo broadcast years. It seems to be the most difficult thing to get working as the originals are solid state using very early germanium transistors that often develop "wiskers", shorting out the transistors. I know you can zap them with several hundred volts to sometimes get them to work again. I had instead bought rare replacements from France so I could just swap them out. With the new working decoder I can concentrate on getting the rest of the set working well.
Here is the original and new FM stereo decoder. With a couple of easy wiring changes you can also use this decoder in the SABA 300 and 400 automatic sets, as well as a few others.
