I also tried my old FET servo some months ago.
The part is a inductor (called "choke coil" in the KO infos) of 4.7 ÁH, and it needs to have a DC resistancee of less than 0.5 Ohms.
Officials Infos from 20 years ago : "set for use with a high-frequency ESC (from 2 to 10 kHz), in order to prevent servo errors or even damage, due to spike noise in the Ni-Cd (+) lead of the high-frequency ESC."
At that time, I used it with a ESC with special wire for FET servo, but I did not test it to see if it was an output with constant current like for BEC, or if it was only wired to +lead.
Now, I tried the same FET servo on two different brushless ESC, and put the inductore between the "FET wire" and + of ESC.
Actually, it's soldered on the + side of my capacitor.
I am not sure your problem comes from that missing part, but better try and install it.
Hope this helps
: did not see that DemonProduct shows a capture of KO infos.
At least, it confirms the one I had from my old manuals.
