I found this out the hard way two days ago when I'd finally gotten round to using it in my DIY GPSDO project. If you remove this "excess baggage", solder blobbing the relevant voltage option links will now produce the indicated voltages. I also discovered,

    it is small well working step-down, but if you want adjustable V, you need to add trimmer
