I have had a couple DEFX projects that absolutely wouldn't work with the Xvive RI parts. Once I replaced them with other 'close enough' vactrols, everything worked great...so I would certainly be suspicious of them!

I also built the GGG one 20+ years ago. There is a power supply schematic at GGG that I followed and have used for multiple bipolar supplies since. It's rock solid. The input is a 35VAC signal, which gets converted to the required +/- 12V DC.
